Question 1

A continuous variable has an infinite number of values that flow along a continuum,while a variable has a fixed set of separate values or categories.

Accepted Answer

The definition given in the question corresponds to the definition of a discrete variable. Therefore, the best choice is D, which represents a discrete variable.

Question 2

Nominal measures indicate a difference among categories.Which of the following would NOT be a nominal measure?

Accepted Answer

IQ scores are not considered nominal measures as they indicate a quantitative value rather than a category or classification. Gender, religion, and political party are all categorical variables and fall under the category of nominal measures.

Question 3

If a unit fits into one category only,it is

Accepted Answer

If a unit fits into one category only, it cannot fit into any other category, making the categories mutually exclusive. This means that each unit can only be classified in one category and not in any others.

Question 4

Marketing researchers often use this scale to measure subjective feelings.

Accepted Answer

The answer of Marketing researchers often use this scale to...

Question 5

This type of validity uses a standard to indicate a concept.In other words it agrees with an external source.What type of validity is it?

Accepted Answer

This is criterion validity, as it is measuring how well a test or measurement correlates with an external criterion or standard.

Question 6

Mr.Marsh asks his colleagues if they believe that his conceptual definition and measurement fit.They agree that they do.What type of validity is this?

Accepted Answer

The scenario indicates that Mr. Marsh's colleagues believe that his conceptual definition and measurement fit, which suggests face validity. Face validity refers to the extent to which a measure appears, on the surface, to measure what it is supposed to measure.

Question 7

All measurement builds on these two processes:

Accepted Answer

Conceptualization involves defining key concepts and variables of interest, while operationalization involves specifying the procedures used to measure or manipulate those variables. These two processes are crucial for developing reliable and valid measurements. Therefore, C is the best choice since it shows the correct order of the two key steps in measurement.

Question 8

Mr.Marsh is measuring temperature in his research.He will be using what variable level of measure?

Accepted Answer

Temperature is measured on a continuous scale, and the differences between the levels are equal (for example, the difference between 20 and 30 degrees is the same as the difference between 70 and 80 degrees). Therefore, temperature is measured at the interval level.

Question 9

An IQ score is an example of what type of measurement?

Accepted Answer

An IQ score is measured on a scale that has equal intervals between each point, but there is no true zero point. Therefore, it falls under the category of interval measurement.

Question 10

When all the items in a scale or index fit together and measure a single concept,this is called

Accepted Answer

Unidimensionality refers to the property of all the items in a scale or index measuring a single concept. This means that each item in the scale is related to the same underlying construct or variable, and can be used together to create a composite score or measure of that construct. Unidimensionality is an important property in measurement and ensures that the scale or index is reliable and valid for measuring the intended construct.

Question 11

This term is used to address how well a researcherȇs measure of reality measures with the ideas she uses to understand that aspect of reality.What is this term?

Accepted Answer

The term being described is validity, which refers to how well a measure actually measures what it intends to measure. Reliability (B) refers to the consistency of a measure, while reality (C) refers to the actual aspects of the world being studied. Value (A) is not relevant to this concept.

Question 12

The Guttman scale measures how well data fit into a

Accepted Answer

The Guttman scale measures how well data fit into a hierarchical pattern, where a respondent is assumed to agree with all items that are less severe than the ones they agree with. It is not used for combination or likert rating.

Question 13

When creating this measure,two or more items are combined into a single numerical score.What is this called?

Accepted Answer

The answer of When creating this measure,two or more items...

Question 14

Dr.Van Offer is measuring all possibilities in his research.His technique is most likely

Accepted Answer

Dr. Van Offer is measuring all possibilities, meaning he is considering every possible option or scenario. Therefore, his technique is exhaustive.

Question 15

This type of validity is easiest to achieve and the most basic kind of validity.It is a judgment by knowledgeable people that the indicator really measures the concept it purports to measure.It is known as

Accepted Answer

Face validity is the type of validity that refers to the degree to which an assessment or tool appears, on its surface, to measure what it is intended to measure. It is usually assessed by expert judgments of whether the content of the measure appears relevant and appropriate for the construct being measured.

Question 16

This type of measurement indicates a difference among categories,and the categories can be ordered or ranked.If a student earned an ȈAȈ,that measurement would be a(n)______________________measurement.

Accepted Answer

The measurement described is an ordinal measurement, which is not listed among the options. Ordinal measurements indicate a difference among categories that can be ordered or ranked, such as letter grades.

Question 17

If Dr.Mottleȇs measurements of her data are consistent and do not vary because of the characteristics of how she measured,the measurement is

Accepted Answer

The measurement is reliable if it is consistent and does not vary due to the characteristics of how it was measured. Validity refers to whether the measurement is actually measuring what it is intended to measure, so this is not the best choice. Time consuming and redundant do not apply to the scenario given.

Question 18

Mr.Marsh uses a special measure combining information from separate indicators into one score.He is most likely using a(n)

Accepted Answer

Mr. Marsh is combining information from multiple indicators into a single score, which is characteristic of an index. An index is a composite measure that combines multiple variables or indicators into one measure of a concept.

Question 19

If Dr.Mottle gives items in an index more or less of a value her index is probably

Accepted Answer

If Dr.Mottle gives items in an index more or less of a value, her index is likely being weighted. Weighting is a statistical technique that assigns different values to different factors based on their relative importance.

Question 20

An example of a continuous variable would be

Accepted Answer

Age is a continuous variable because it can take on any value within a certain range (e.g. 0-100 years old) and can also be measured with decimal places (e.g. 23.5 years old). Gender, pregnant/not pregnant, and a light switch are not continuous variables. Gender and pregnant/not pregnant are categorical variables, and a light switch is a binary variable (on/off).
