Question 1

Which of the following alternatives is not an example of a rating scale?
A)Paired comparison.
B)Likert scale.
C)Semantic differential scale.
D)Stapel scale.

Accepted Answer

Paired comparison is a comparative method in which two alternatives are presented to the respondent and they must choose one over the other. It is not a rating scale as it does not involve assigning a score or rating to an item or concept. The other three alternatives (B, C, and D) are examples of rating scales as they require respondents to indicate their level of agreement, attitude, or preference on a scale.

Question 2

The scale type of a moderating variable is nominal.

Accepted Answer

False

Question 3

"As the calibration or fine-tuning of a scale increases in sophistication,so does the power of the scale".What is therefore the most powerful scale?
A)A nominal scale.
B)An ordinal scale.
C)An interval scale.
D)A ratio scale.

Accepted Answer

A ratio scale is the most powerful type of scale as it not only allows for ordering and measuring the distance between values (like an interval scale), but also has a fixed and meaningful zero point, meaning that ratios between values can be calculated (e.g. one value is twice or half of another). This level of precision and ability to make meaningful comparisons between values makes it the most powerful scale.

Question 4

With which allows us to calculate a mode and a median,but not a mean?
A)A nominal scale.
B)An ordinal scale.
C)An interval scale.
D)A ratio scale.

Accepted Answer

An ordinal scale allows for the calculation of a mode and a median because it involves ordered categories, but it does not allow for the calculation of a mean since the intervals between the categories are not equal or known.

Question 5

A characteristic of a ratio scale is that it has an absolute zero point.

Accepted Answer

A ratio scale has a true zero point which denotes the absence of the characteristic being measured. For example, in a weight scale, a weight of 0 means there is no weight at all. This is the absolute zero point.

Question 6

About a scale (set of questions)it can be said that it is if it measures what it purports to measure.
A)Reliable.
B)Accurate.
C)Valid.
D)Consistent.

Accepted Answer

Validity refers to the extent to which a scale measures what it is intended to measure. Reliability refers to the consistency of results obtained by a scale. Accuracy refers to how closely the scale measures the true value of what it is supposed to measure. Consistency refers to the degree to which the scale produces the same results over time. While reliability, accuracy, and consistency are also important aspects of a scale, validity is the most important because if a scale does not measure what it is intended to measure, then it is not useful.

Question 7

What is the type of scale of the variable 'age' if it is measured in the following way? "What is your age? ____ years."
A)Nominal.
B)Ordinal.
C)Interval.
D)Ratio.

Accepted Answer

The variable 'age' is measured in terms of years and has a true, meaningful zero point (i.e., age 0). Therefore, it is a ratio scale measurement.

Question 8

What is the measurement level of the following question? "What is your gross income per month? € "
A)Non-metric.
B)Interval.
C)Ratio.
D)None of the above.

Accepted Answer

This question is measuring a continuous variable (income) and asks for a specific value in a specific unit (monthly gross income in euros), making it a ratio level measurement.

Question 9

What is the measurement level of income,measured in the following way: "What is your annual gross income?"
< €15.000
€20)000 - €30.000
€30)000 - €45.000
> € 45.000
A)Nominal.
B)Ordinal.
C)Interval.
D)Ratio.

Accepted Answer

The income categories are presented in a specific order, indicating an ordinal measurement level. However, it is important to note that the categories do not have equal intervals between them and there is no true zero point, which would be necessary for a ratio measurement level.

Question 10

Formally,a Likert scale is _______?
A)A nominal scale.
B)An ordinal scale.
C)An interval scale.
D)A ratio scale.

Accepted Answer

A Likert scale is an example of an ordinal scale, which measures the degree of agreement or disagreement with a statement or item. It involves a fixed range of responses ranging from "strongly agree" to "strongly disagree," with each response given a numerical value for analyses. In an ordinal scale, the numerical values are meaningful only in terms of their order, but not in terms of the actual values.

Question 11

About a scale (set of questions)it can be said that the indicates how well the results obtained from the use of the measure fit the theories around which the test is designed.
A)Content validity.
B)Construct validity.
C)Criterion-related validity.
D)Stability.

Accepted Answer

Construct validity refers to how well a scale measures the theoretical construct or idea that it is designed to measure. It assesses whether the scale accurately reflects the underlying concept or theory being tested.

Question 12

The following scale is a: "Ugly __ __ ??__ __ __ Beautiful"
A)A likert-scale.
B)A semantic differential scale.
C)A numerical scale.
D)An itemized rating scale.

Accepted Answer

The scale is a semantic differential scale because it has two opposing adjectives (ugly and beautiful) with blank spaces in between where respondents can place their ratings on a continuum.

Question 13

Interval and ratio variables are also called metric variables.

Accepted Answer

Interval and ratio variables are both types of metric variables, which are quantitative variables that have a numerical scale with equal intervals.

Question 14

The difference between an ordinal and a ratio scale is that a ratio scale has an arbitrary zero point.

Accepted Answer

The statement is backwards. A ratio scale has a true zero point, whereas an ordinal scale has no true zero point and the numbers are merely ranks or orders.

Question 15

Army rank (such as lieutenant,captain,major,colonel,general,etc. )is ordinal in nature.

Accepted Answer

Army rank is an ordered category, with each rank being higher or lower than another. It follows a clear hierarchy, with each rank having specific duties and responsibilities. This makes it an example of an ordinal scale measurement.

Question 16

Temperature is usually measured on a ratio scale.

Accepted Answer

The answer of Temperature is usually measured on a ratio...

Question 17

Which of the following scales is not a ranking scale?
A)Paired comparison.
B)Forced choice.
C)Comparative scale.
D)Stapel scale.

Accepted Answer

Stapel scale is not a ranking scale, it is a unipolar rating scale that measures the position of a respondent's attitude towards an object or concept. A ranking scale, on the other hand, requires respondents to order items in terms of preference, importance, or other criteria. Paired comparison, forced choice, and comparative scale are all ranking scales.

Question 18

A nominal scale is always dichotomous.

Accepted Answer

A nominal scale is a measurement scale that categorizes data into mutually exclusive and exhaustive categories or groups, but it can have more than two categories. It does not have any inherent order or numerical value.

Question 19

Convergent validity is established when the scores obtained with two different instruments measuring the same concept are highly correlated.

Accepted Answer

Convergent validity is indeed established when the scores obtained with two different instruments measuring the same concept are highly correlated.

Question 20

Julia stands on a pair of scales three times in a row.The first time she weighs 69 kilo,the second time 69 kilo,and the third time 69 kilo.Her real weight is 51 kilo.What is the matter with the scales?
A)The pair of scales is not reliable and not valid.
B)The pair of scales is reliable but is not valid.
C)The pair of scales is not reliable but is valid.
D)The pair of scales is reliable and valid.

Accepted Answer

The scales are reliable as they give the same reading all three times Julia weighs herself. However, they are not valid as they give a weight reading that is significantly higher than Julia's real weight of 51 kilos.
