________ is assessed when the data on the scale being evaluated on the criterion variables are collected at the same time.

An important property of coefficient alpha is that its value tends to decrease with an increase in the number of scale items.

Which of the following statements is not a consideration when making non-comparative itemized rating scale decisions?

A multi-item scale should be evaluated for accuracy and applicability. This involves an assessment of all of the following except ________.

A measure is perfectly reliable if ________.

Which scale asks the respondent to indicate how accurately or inaccurately each term describes the object by selecting an appropriate numerical response category?

Given its subjective nature, content validity alone is a sufficient measure of the validity of a scale.

The scale descriptors "never," "rarely," "sometimes," "often," and "very often" are commonly used when studying the ________ construct (Table 9.3 in the text).

When determining the number of scale categories to use in a non-comparative itemized rating scale, the nature of the object is relevant.

Which statement is true if deciding on the number of scale categories to use in a non-comparative itemized rating scale?

Coefficient alpha assists in determining whether the averaging process used in calculating coefficient beta is masking any inconsistent items.

In a ________, respondents rate the objects by placing a mark at the appropriate position on a line that runs from one extreme of the criterion variable to the other.

Which statement is not true when deciding on whether to use balanced or unbalanced scales when developing a non-comparative itemized rating scale?

When determining the number of scale categories to use in a non-comparative itemized rating scale, if individual responses are of interest, or the data will be analyzed by sophisticated statistical techniques, five or more scale categories may be required.

A scale designed to measure store image would be considered inadequate if it omitted any of the major dimensions (quality, variety, assortment of merchandise, etc.). This inadequacy would be reflected in the ________ of the scale.

The ________ is confusing and difficult to apply. It is the least used of the itemized scales.

The smaller the number of scale categories, the finer the discrimination among stimulus objects that is possible.

________ is the degree to which a study based on a sample applies to a universe of generalizations.

Which itemized rating scale takes longer to complete than other itemized rating scales because respondents have to read each statement?

Reliability refers to the extent to which a scale produces valid results if repeated measurements are made.
