Exam 9: Measurement and Scaling: Non Comparative Scaling Techniques

In ________ the degree of similarity between two measurements is determined by computing a correlation coefficient.The higher the correlation coefficient,the greater the reliability.

Deciding whether to present scales as vertical or horizontal is related to which of the non-comparative itemized rating scale decisions?

Which non-comparative scale has the advantage of being easy to construct and the disadvantage of cumbersome scoring unless the scoring is computerized (Table 9.1 in the text)?

Figure 9.4 in the text showed the development of a multi-item scale.Discuss the development process.

The data obtained by using a Stapel scale can be analyzed in the same way as a ________.

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.

Which statement about generalizability is not true?

A ________ is a scale for measuring attitudes that consists of a single adjective in the middle of an even-numbered range of values,from -5 to +5,without a neutral point (zero).

The Stapel scale is usually presented horizontally.

Using several scale items to measure the characteristic of interest provides more accurate measurement than a single-item scale.

________ is the extent to which a scale produces consistent results if repeated measurements are made on the characteristic.

Which statement is not true regarding the relationship between reliability and validity?

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

Reliability can be defined as the extent to which measures are free from random error,XR.

________ is a type of construct validity that assesses the extent to which a measure does not correlate with other constructs from which it is supposed to differ.

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

Systematic sources of error do have an adverse impact on reliability because they affect the measurement in a constant way and do not lead to inconsistency.

Perfect validity requires that there be no measurement error,therefore: (XO = XT,XR = 0,XS = 0).

Individual items on a semantic differential scale may be scored on either a -3 to +3 or a 1 to 7 scale.

It has been found that providing a verbal description for each scale category consistently improves the accuracy or reliability of the data.
