Question 3

What are the two factors that drive the use of multiple-item scales in research?

Accepted Answer

The answer of What are the two factors that drive...

Question 4

Only ordinal data can be obtained using rank-order scales.

Accepted Answer

Rank-order scales are used to obtain ordinal data, which is a type of categorical data that can be ranked or ordered based on a particular characteristic or attribute. The rankings on these scales indicate the relative position or order of the items being compared, but they do not indicate the actual magnitude or distance between different ranks or categories. Therefore, only ordinal data can be obtained using rank-order scales.

Question 5

The number of dimensions of a construct influences the decision to use a single-item versus a multiple-item scale.

Accepted Answer

When a construct is multidimensional, multiple items are needed to capture all dimensions. In contrast, if a construct is unidimensional, a single item may be sufficient.

Question 6

A graphic rating scale is a type of comparative rating scale.

Accepted Answer

A graphic rating scale is a type of absolute rating scale, where each employee is rated independently against a fixed set of criteria, not in comparison to others.

Question 7

What are the requirements of designing measurement scales?

Accepted Answer

The answer of What are the requirements of designing measurement...

Question 8

Internal consistency reliability values for single-item or two-item scales cannot be accurately determined and should not be reported as representing the scale's internal consistency.

Accepted Answer

Internal consistency reliability values, such as Cronbach's alpha, are calculated based on the intercorrelations among multiple items in a scale. Single-item or two-item scales do not have multiple items to calculate intercorrelations and therefore, calculating internal consistency reliability is not appropriate. Therefore, it is not accurate to report internal consistency reliability values for single-item or two-item scales.

Question 9

A researcher wants to measure the temperature (in degree Fahrenheit) inside a grocery store at which the customers feel most comfortable. Suggest a scale that the researcher can use. Why is it not possible to use the ratio scale in this case?

Accepted Answer

The answer of A researcher wants to measure the temperature...

Question 10

Constant-sum scales should preferably use more than seven attributes.

Accepted Answer

Constant-sum scales typically use fewer attributes to avoid overwhelming respondents and to ensure more accurate distribution of points among the attributes.
