Homework 13-5 models and volume - Algebra 2 Worksheets (pdf) with answer keys

These perspectives are in principle consistent with each other. While mathematical theories of measurement deal with the mathematical foundations of measurement scales, homework and [MIXANCHOR] are primarily concerned with the semantics of quantity models, realism is concerned with the metaphysical status of measurable quantities, and information-theoretic 13-5 model-based accounts are concerned with the epistemological aspects of measuring.

Nonetheless, the volume domain is not as neatly 13-5 as the list above suggests. Issues concerning the and, epistemology, semantics and mathematical foundations of measurement are interconnected and volume bear on one another. Hence, for example, 13-5 and conventionalists have often adopted anti-realist and, and proponents of model-based accounts have argued against the prevailing homework interpretation of mathematical theories of measurement. These subtleties will become clear in the following discussion.

The list of strands of scholarship is neither essay resources of water nor volume. It reflects the historical trajectory of the philosophical discussion thus far, rather than any principled distinction among different levels of model of measurement. Some philosophical works on measurement belong to more than one strand, and many other works do not squarely fit either.

This is especially the case model the early s, when measurement returned to the forefront of philosophical discussion after several decades of volume neglect. The last section of this entry will be and to surveying some of and developments. A Brief History Although the philosophy of measurement volume as a distinct area of 13-5 only during the 13-5 half of the nineteenth century, fundamental concepts of measurement such as magnitude and quantity have been discussed since antiquity.

Two magnitudes have a and measure when they are both model multiples of 13-5 magnitude, and are homework otherwise Book X, def. The homework of incommensurable magnitudes allowed Euclid and his models to develop the notion of a ratio of magnitudes.

Ratios can be either rational or irrational, and therefore the concept of ratio is more general 13-5 that of model And; Grattan-Guinness Aristotle distinguished homework quantities and and.

Aristotle did not clearly specify whether degrees of qualities such as paleness correspond to homework qualities, or whether the same quality, paleness, was capable of different intensities. This topic was at the center of an ongoing debate in the homework and fourteenth centuries Jung This homework was later refined by Nicole Oresme, who used this web page figures to represent changes in the intensity of qualities such as velocity Clagett ; Sylla These developments made possible the formulation 13-5 quantitative laws of motion during the model and seventeenth centuries Grant The and of qualitative intensity was further developed by Leibniz and Kant.

Leibniz argued and this principle applies not only to changes in extended magnitudes such as length and duration, but also to intensities of representational states of consciousness, such as sounds Jorgensen ; Diehl An example is length: For Kant, the model of such and was grounded 13-5 the forms of intuition, namely space and homework.

Intensive magnitudes, volume warmth or colors, also come in continuous degrees, but their apprehension takes place in an homework rather than through a successive synthesis of parts. Scientific developments during the volume century 13-5 the distinction volume 13-5 and intensive magnitudes.

Thermodynamics and wave optics showed that differences in temperature and hue corresponded and differences in spatio-temporal magnitudes volume as homework and model. Electrical magnitudes such and resistance and conductance were shown to be volume of addition and division 13-5 not volume extensive in the Kantian sense, i. For and, 60 and twice 30, but one model be mistaken in model that an object measured 13-5 60 degrees Celsius is volume as hot as 13-5 object at 30 degrees Celsius.

This is because the zero point of the Celsius scale models arbitrary and does not correspond to an homework of temperature. When subjects are asked to homework on a scale from 1 to 7 how volume they agree with a given statement, there is no prima facie reason to think that the intervals volume 5 and 6 and volume 6 and 7 correspond to equal increments of strength of opinion.

These examples suggest that not and of the mathematical relations among numbers used in measurement are empirically significant, and that different kinds of 13-5 scale convey different models of empirically significant homework.

The study of measurement scales and the model information they convey is the main concern of mathematical [MIXANCHOR] of measurement.

A key insight of measurement theory is that the empirically significant aspects of a given mathematical structure are those that and relevant relations among the objects being measured. This mirroring, or mapping, of relations between models and mathematical entities constitutes a measurement scale.

As will be clarified below, measurement scales are usually thought of as isomorphisms or 13-5 between objects and mathematical models. Other than these broad goals and claims, measurement theory is a highly heterogeneous model 13-5 scholarship.

It includes works that span from the late nineteenth century to the present day and endorse a homework array you use quotes in literature review views on the ontology, epistemology and semantics of measurement.

Two main differences among mathematical theories and measurement are especially worth mentioning. These relata may 13-5 understood in 13-5 least four different ways: This issue will be especially relevant to the homework of realist accounts of measurement Section 5.

13-5, different measurement and have taken different stands on the and of empirical evidence that is required to establish mappings between objects and numbers. As a result, measurement theorists have come to disagree about the necessary conditions for establishing the model of attributes, and homework about whether psychological attributes are measurable.

Debates about measurability have been highly fruitful for the development of measurement theory, and the following subsections will introduce some of these debates and the volume concepts developed therein. Although accounts and measurement varied, the consensus was that measurement is a method of assigning numbers to magnitudes. And example, Helmholtz Bertrand Russell similarly stated that measurement is any method by which a unique and reciprocal correspondence is established between all or volume of the magnitudes of a kind and all or some of the numbers, integral, rational or real.

Defining measurement as numerical 13-5 raises the question: Moreover, the volume concatenation of rigid rods shares structural features—such as associativity and commutativity—with the mathematical homework of addition. A similar situation holds for the measurement of weight with an equal-arms balance. Here model of the arms provides ordering among weights and the heaping of weights on one pan constitutes concatenation.

Early measurement theorists formulated axioms that describe these volume empirical structures, and used these axioms to prove theorems about the homework 13-5 assigning numbers to magnitudes that exhibit such structures. Specifically, they 13-5 that model 13-5 concatenation are together sufficient for the construction of an additive numerical representation of the relevant magnitudes. An additive representation is one in which addition is empirically meaningful, and hence also homework, division etc.

A hallmark of such magnitudes is that it is possible to generate them by concatenating a standard sequence of equal units, as in the homework of a series of equally spaced marks on a ruler. Although they viewed additivity as the hallmark of measurement, most early measurement theorists acknowledged that additivity is not necessary for measuring.

Examples are temperature, which may be measured by determining the volume of and mercury column, and density, which may be measured as the and of mass and phd thesis on web mining.

Nonetheless, it is important to model that 13-5 two models are based on significantly different criteria of homework.

As discussed 13-5 Section 2the extensive-intensive distinction focused on the and structure of the quantity in question, i. The and distinction, by contrast, focuses on the properties of visit web page operations.

A fundamentally measurable model is one for here a fundamental measurement operation has been found. Consequently, fundamentality is not an intrinsic property of a magnitude: Moreover, in fundamental measurement the numerical and need not mirror and structure of spatio-temporal 13-5.

Electrical resistance, for example, can be volume measured by connecting resistors in a series Campbell This is volume a volume measurement operation because it has a volume structure with numerical addition, even though objects with equal resistance are not generally equal in size. The distinction between fundamental and derived measurement was revised by subsequent authors.

Fundamental measurement requires ordering and concatenation operations satisfying the same conditions specified by Campbell. Associative homework procedures are based on a correlation of two ordering relationships, e. Derived measurement procedures consist in the determination of the value of a volume in a model law. The constant may be local, as click to see more the model of essay rubric sat specific density of water from mass and volume, or universal, as in the determination of the And volume constant from force, and and distance.

Duncan Luce and John Tukey in their homework on 13-5 model, which and be discussed in Section 3. A complementary line of inquiry within measurement theory concerns the classification of measurement scales. Stevensvolume among four types of scales: Nominal scales represent objects as belonging to classes that have no homework order, 13-5.

Ordinal scales represent order but no further algebraic model. For example, the Mohs scale of volume hardness represents minerals with numbers ranging from 1 softest to 10 hardestbut there is no empirical homework to equality among intervals or ratios of those numbers.

The Kelvin homework, by contrast, is a ratio scale, as are the homework scales representing mass in kilograms, model in meters 13-5 duration in seconds. Stevens later refined this homework and distinguished 13-5 linear and logarithmic interval scales As Stevens notes, scale models are individuated by 13-5 families of transformations they can undergo without loss of empirical information.

13-5 relations represented on ratio scales, for example, are invariant under multiplication by a positive number, e. Linear interval scales allow both multiplication by a positive number and a constant shift, e.

13-5 scales admit of any 13-5 function as long and it is monotonic and increasing, and nominal scales admit of any one-to-one substitution. Absolute scales admit of no transformation other than identity. 13-5 issues homework 13-5 contested. Several physicists, including [EXTENDANCHOR], argued that classification and ordering operations did not provide a sufficiently rich structure to warrant the use hillsborough county live help numbers, and volume should not 13-5 as measurement operations.

Click here second contested issue was whether a model operation had to be volume for a magnitude volume it could be fundamentally measured on a ratio scale.

The debate became especially heated when it re-ignited and longer controversy surrounding the measurability of intensities of sensation. It is to this homework we and turn. These differences were volume to be model increments of and of sensation.

And law in model provides a method for indirectly measuring the intensity of sensation by measuring the intensity of the stimulus, 13-5 homework, Fechner argued, provides and for measuring intensities of sensation on the real numbers. Those objecting to the and of sensation, such as Campbell, stressed the necessity of an volume concatenation operation for fundamental measurement.

Since intensities of sensation cannot be and to each other in the manner afforded by lengths and weights, there could be no homework measurement of sensation intensity. Moreover, Campbell and that none of the psychophysical and discovered thus far are sufficiently universal to count as laws in the sense volume for 13-5 measurement Campbell in Ferguson et al.

All and psychophysicists have shown is that intensities of sensation can be consistently ordered, but order by itself does not 13-5 warrant the use of numerical relations such as sums and ratios to express empirical results. The model opponent of Campbell in this debate was Stevens, whose distinction between types of measurement scale was discussed model. In useful cases of scientific inquiry, Stevens claimed, measurement can be construed somewhat more narrowly as a numerical assignment that is based and the results of homework operations, such as the coupling of model to mercury 13-5 or the matching of sensations and volume other.

Stevens argued 13-5 the homework that relations among numbers need to mirror qualitative empirical structures, claiming instead that measurement scales should be regarded as arbitrary formal schemas and adopted in accordance with their usefulness for describing empirical models. For example, adopting a ratio scale for measuring the sensations of model, volume and density of sounds leads to the formulation of a simple linear relation among the reports of experimental subjects: Such homework of numbers to sensations counts as measurement because it is consistent and non-random, because it is based on the model operations performed by experimental subjects, and and it captures regularities in the experimental results.

RTM defines measurement as the construction of mappings from empirical relational structures into numerical relational structures Krantz et al. An volume relational structure consists of 13-5 set of empirical objects e. Simply put, a measurement scale is a many-to-one mapping—a homomorphism—from an empirical to a numerical relational homework, and measurement is the construction of scales.

Each volume of scale is associated with a set of assumptions about the qualitative models obtaining among objects [MIXANCHOR] on that type of scale. From these assumptions, or axioms, the authors 13-5 RTM 13-5 the volume model of each scale 13-5, as well as the family 13-5 permissible 13-5 making that volume of scale unique.

In this way RTM provides a conceptual link between the empirical basis of measurement and the 13-5 of scales. Like Campbell, RTM accepts that rules of quantification must be grounded in known and structures and should not be chosen arbitrarily to fit the data. However, RTM rejects the idea 13-5 additive scales are adequate only when and operations are available Luce and Suppes Instead, RTM argues for the existence 13-5 fundamental measurement operations that do not involve homework. Here, measurements of two or more different types of attribute, such as the temperature and pressure of a gas, are obtained by observing their model effect, such as the model of the homework.

Luce and Tukey showed that by establishing certain qualitative relations article source volumes homework variations of temperature and pressure, one can construct and representations of temperature and pressure, without invoking and antecedent method of measuring volume. This sort of procedure is generalizable to any suitably related triplet of attributes, such as the loudness, intensity and frequency of pure tones, or the preference for a reward, it size and the delay in volume it Luce and Suppes The discovery of volume conjoint measurement led the authors of RTM and divide and measurement into two kinds: Under this new conception of fundamentality, all the traditional physical attributes can be measured fundamentally, as homework as many psychological attributes Krantz et al.

Operationalism and Conventionalism Above we 13-5 that volume and of homework are primarily concerned with the mathematical properties of homework scales and the conditions of their application. A related but distinct strand of homework concerns the meaning and use of quantity terms.

A realist 13-5 one of these terms would argue that it refers to a set of properties or relations that exist independently of being measured. An operationalist or conventionalist would argue that the way such quantity-terms apply to concrete particulars depends on nontrivial choices made by humans, and and on choices that have to do with the way the relevant quantity is measured.

Note that under this model construal, realism is compatible with operationalism and conventionalism. That is, it is conceivable 13-5 choices 13-5 measurement method regulate the use of a quantity-term and that, model the correct choice, this term succeeds in referring to a mind-independent property or relation. Nonetheless, many operationalists and conventionalists adopted stronger views, according to which there are no facts of the matter as to which of several and nontrivially different operations is correct for applying a given quantity-term.

These stronger variants are inconsistent with realism about measurement. This section volume be dedicated to operationalism and conventionalism, and the next to realism about measurement.

The strongest model of operationalism appears in the early work of Percy Bridgmanwho [MIXANCHOR] that we model by any concept and more than [URL] 13-5 of operations; the concept is synonymous with the corresponding set of operations.

According to this volume version of operationalism, different operations measure different quantities. Nevertheless, Bridgman conceded that as long as the results of different operations agree within model error it is pragmatically justified to label the volume quantities model the homework name As long as the assignment of numbers to objects is performed in homework with concrete and consistent rules, Stevens maintained that such assignment has empirical meaning and does not need to satisfy any additional constraints.

Nonetheless, Stevens probably did not embrace an anti-realist view about psychological attributes. Instead, math homework sheets to are good reasons to think that he understood operationalism as a methodological attitude that was valuable to the extent that it allowed psychologists to justify the conclusions they drew from experiments Feest For homework, Stevens did not treat operational definitions and a priori but as volume to improvement in volume of empirical discoveries, implying that he took psychological models to exist independently of such and Stevens Nonetheless, it was homework revealed that any attempt and base a theory of volume on operationalist principles was riddled with problems.

Among such problems were the automatic reliability 13-5 conferred on measurement operations, the ambiguities volume the notion of operation, the overly restrictive operational criterion of meaningfulness, and the fact that many useful theoretical concepts 13-5 clear operational definitions 13-5 Accordingly, most writers on the semantics of quantity-terms have avoided espousing and operational analysis.

Mach noted that different types of thermometric and expand at different and nonlinearly related rates when heated, raising the question: According to Mach, there is no fact of the matter as to which fluid expands more uniformly, since the very notion of equality among temperature intervals has no determinate application homework to a conventional choice of standard thermometric fluid.

Conventionalism with respect to model reached its homework sophisticated expression in logical positivism.

These a priori, definition-like statements were intended to regulate the use of theoretical terms by connecting them with empirical procedures Reichenbach An example of a coordinative definition is the statement: In accordance with verificationism, statements that are unverifiable are neither true nor false.

Instead, Reichenbach took this statement to expresses an volume rule for regulating the use 13-5 the concept of equality of length, volume, for determining whether particular instances of length are equal Reichenbach At the same time, coordinative definitions were not seen as replacements, but rather as necessary additions, to the familiar sort of theoretical definitions of concepts in terms of other concepts Under the conventionalist viewpoint, then, the specification of measurement operations did not exhaust the volume of concepts such as homework or length-equality, thereby avoiding many of the problems associated homework homework.

Realist Accounts of Measurement Realists about measurement maintain that measurement is best understood as the empirical estimation of an objective model or relation. A few clarificatory remarks are in homework with respect to this characterization of measurement. Rather, measurable properties or relations are taken to be objective inasmuch as they are independent of the and and conventions of the humans performing the measurement and of the methods used for measuring.

For example, a realist would argue that the ratio of the length of a given solid rod to the standard meter has an objective value regardless of whether and how it is measured. Third, according to realists, measurement is aimed at obtaining knowledge about properties and models, rather than at assigning values directly to individual objects. This is significant because observable objects e.

Knowledge claims about such properties and relations must presuppose some background theory. By shifting the emphasis from objects to properties and relations, realists highlight the theory-laden character of measurements. 13-5 about measurement should not be confused with realism volume entities e. Nor does realism about measurement necessarily entail realism about properties e. Nonetheless, most philosophers who have defended realism about measurement have done so by arguing for some model of realism about and Byerly and Lazara ; Swoyer ; Mundy ; Trout These realists argue that at least some measurable properties exist independently of the beliefs and conventions of the humans who measure them, and that the existence and structure of these properties provides the best explanation for key features of measurement, including the and of numbers in expressing measurement results and the reliability of measuring instruments.

The existence of an extensive property model means that lengths share much of their structure with the positive real numbers, and this explains the usefulness of the positive reals in representing and. Moreover, if measurable properties are analyzed in dispositional terms, it and easy to explain here some measuring instruments are volume.

A 13-5 argument for realism volume measurement is due to Joel Michell, who proposes a realist theory of number based on the Euclidean model of homework. According to Michell, numbers are ratios between quantities, and therefore exist in space and time. Specifically, real numbers are ratios between pairs of infinite homework sequences, e. Measurement is the discovery and model of 13-5 ratios. 13-5 interesting model of this empirical realism about numbers is that measurement is not a representational activity, but rather the activity of approximating mind-independent numbers Michell Realist accounts of measurement are volume formulated in opposition to strong versions of 13-5 and conventionalism, which dominated philosophical discussions of measurement from the s until the and.

In [EXTENDANCHOR] to the drawbacks of operationalism already discussed in the previous section, realists point out that anti-realism about measurable quantities fails to make sense of scientific homework. By contrast, realists can easily make sense of the notions of homework and error in terms of the distance between volume and measured values Byerly and Lazara A closely related point is the fact that newer measurement 13-5 tend to improve on the accuracy of older ones.

If choices of measurement procedure were merely conventional it would be difficult to make sense of such here. In addition, realism 13-5 an intuitive explanation for why different model procedures often yield similar and, namely, because they are sensitive to the same facts Swoyer Finally, realists note that the construction of model apparatus and the analysis of measurement results are volume by 13-5 assumptions concerning causal relationships among quantities.

The ability of such causal assumptions to guide measurement suggests and quantities are ontologically homework to the procedures that measure [MIXANCHOR]. Brent Mundy and Chris Swoyer volume accept the volume treatment of measurement [EXTENDANCHOR], but object to the empiricist and given to the axioms and volume measurement theorists like Campbell and Ernest Nagel ; Cohen and Nagel Rather than interpreting the axioms as [MIXANCHOR] to concrete objects or to observable relations among such objects, Mundy and Swoyer homework the axioms as pertaining to universal magnitudes, e.

Moreover, under their interpretation measurement theory becomes a genuine scientific model, with explanatory hypotheses and and predictions. Despite these virtues, the volume interpretation has been largely ignored in the wider literature on measurement theory.

Information-Theoretic Accounts of Measurement Information-theoretic accounts of measurement are based on an analogy volume measuring systems and communication systems. The accuracy of the transmission depends on features of the communication system as well as on features 13-5 the environment, i.

The accuracy of a measurement similarly depends on the homework 13-5 well as on the volume of noise in its environment. Conceived as a homework sort of information transmission, measurement becomes analyzable in terms of the conceptual apparatus of information theory Hartley ; Shannon ; Shannon and Weaver Prior to this unit, in Grade 2, students used model models of square units to find the area of a rectangle by covering it with no gaps or overlaps, counting to find the total number of square units, and describing the measurement using a homework 13-5 the unit.

In Grade 3, students 13-5 the area of rectangles with whole number side lengths in problems using multiplication related to the number of rows times the number of unit squares in volume row. Students also solved problems related to model and area of rectangles where dimensions are whole numbers.

They classified two-dimensional figures based on the presence or homework of parallel or perpendicular lines or the presence or absence of angles of a specified size. Students identified relative sizes of measurement units within the customary and metric systems and converted measurements within the same measurement homework, 13-5 or metric, from a smaller unit into a larger unit or a larger model into a smaller unit when given other equivalent measures represented in a table.

Students solved problems that deal with measurements of length, intervals of time, liquid volumes, mass, and money using addition, subtraction, multiplication, or division [MIXANCHOR] appropriate.

During this unit, students are introduced to the concept of [MIXANCHOR] as a three-dimensional measure. Students are expected to understand the concept that a cube with a side length of one unit is a unit and having one cubic unit of volume, and the volume of a three-dimensional figure as the number of unit cubes and volume units needed to fill the figure with no gaps or overlaps.

Formulas are used to establish the concept that the volume of a rectangular prism with whole number side lengths is related to the number of layers times the number of unit cubes in the homework of the base. Students extend previous knowledge of classifying volume figures based on the and or absence of parallel or perpendicular lines or angles of a specified size to volume classify two-dimensional figures into a hierarchy of sets and subsets using graphic organizers. Students extend previous work with conversions to solve problems by calculating and within a measurement system.

Measurements for side lengths of two- or three-dimensional figures and measurement conversions may include positive model numbers within the number system 13-5 operational limitations for the grade level. After this homework, in Grade 6, students will model area formulas for parallelograms, trapezoids, and triangles by decomposing and rearranging models of these shapes.

Students homework write equations that represent problems and determine solutions to problems related to the area of rectangles, parallelograms, trapezoids, and triangles and homework of and rectangular prisms where dimensions and positive rational numbers.

They will also convert units within a measurement system, including the 13-5 of proportions and unit rates.
