Question 1

Mathematical operations cannot be performed with numbers from nominal scales.

Accepted Answer

While it is true that mathematical operations can be performed with numbers from nominal scales,the result may not have a great deal of meaning.

Question 2

Research would be impossible without measurement.

Accepted Answer

Measurement allows researchers to obtain and record data accurately, making research possible. Without measurement, there would be no way to quantify or compare data, making research impossible.

Question 3

In ratio scales,the location of the zero point is arbitrary.

Accepted Answer

Ratio scales have an absolute zero.This is what distinguishes a ratio scale from an interval scale because zero in a ratio scale has meaning in that it represents an absence of some concept.

Question 4

Concrete measures are those that take on only one of a finite number of values.

Accepted Answer

These are discrete measures.

Question 5

An ordinal scale is the simplest type of measurement scale.

Accepted Answer

A nominal scale is the most elementary level of measurement.

Question 6

Measurement is the process of describing some property of a phenomenon,usually by assigning numbers,in a reliable and valid way.

Accepted Answer

Measurement is indeed the process of describing some property of a phenomenon, usually by assigning numbers, and it must be done in a reliable and valid way to ensure accurate results.

Question 7

Interval scales represent the absolute meaning of the numbers on the scale.

Accepted Answer

Ratio scales do this.Interval scales do capture information about differences in quantities of a concept,though.

Question 8

In measurement,whenever a number is used to assign a value to an observation,the researcher must assign this number according to some predetermined rule.

Accepted Answer

This is true because measurement requires a standardized system for assigning values, whether it be a scale, unit, or other predetermined rule. This ensures that observations can be compared and analyzed in a meaningful way.

Question 9

In marketing research,it is often true that there are several ways in which a concept can be measured.

Accepted Answer

There are often multiple measures or methods that can be used to assess a particular concept in marketing research, such as self-report surveys, behavioral observations, physiological responses, or purchase data. The choice of measure(s) will depend on the research objectives, the type of data needed, the level of precision desired, and the resources available.

Question 10

The most sophisticated form of data analysis for a nominal scale is the average of the scores.

Accepted Answer

Nominal scale properties mean the numbering system simply identifies things,so mathematical functions like averaging should not be performed.

Question 11

"Money" is an example of a ratio scale.

Accepted Answer

Money is measured on a ratio scale because it has a true zero point (i.e. 0 dollars means nothing) and equal intervals between values (a difference of 10 dollars is the same as a difference of 10,000 dollars).

Question 12

All measurement,particularly in the social sciences,contains error.

Accepted Answer

All measurement, particularly in the social sciences, is prone to measurement error. This is because social phenomena are complex, multifaceted, and constantly changing, making it difficult to capture them accurately with any one measure or instrument. Sources of error include measurement bias, sampling error, response error, and data processing errors, among others. It is important for researchers to acknowledge and account for these sources of error in their studies to ensure the validity and reliability of their results.

Question 13

A scale can be thought of as a generalized idea that represents something of meaning.

Accepted Answer

This is a concept.Scales measure concepts.

Question 14

The problem with measurement is that researchers cannot account for errors statistically.

Accepted Answer

Researchers can sometimes account for errors statistically.

Question 15

A construct is a term used for concepts that are measured with single variables.

Accepted Answer

Constructs are measured with multiple variables.

Question 16

Continuous measures are those assigning values anywhere along some scale range in a place that corresponds to the intensity of some concept.

Accepted Answer

Continuous measures involve assigning values to a scale that can cover a wide range and correspond to the intensity of a concept, making the statement true.

Question 17

Correspondence analysis is the process of identifying scale devices that correspond to properties of a concept involved in a research process.

Accepted Answer

This is called operationalization.

Question 18

The Fahrenheit temperature scale is an example of a ratio scale.

Accepted Answer

It is an example of an interval scale.

Question 19

Operational definitions translate conceptual definitions into measurement scales.

Accepted Answer

Operational definitions provide clear and measurable definitions for abstract concepts, allowing researchers to collect data and test hypotheses.

Question 20

A measurement scale in which respondents are asked to rank items based on their preferences is called a nominal scale.

Accepted Answer

This is an ordinal scale.
