Exam 9: Measurement and Scaling: Non Comparative Scaling Techniques

What are some of the ethical responsibilities of researchers when they are developing scales?

________ is a measure of internal consistency reliability that is the average of all possible split-half coefficients resulting from different splittings of the scale items.

Explain how continuous rating scales can be easily implemented on the Internet.

What is the appropriate way to assess the internal consistency of a multi-item scale with sets of items designed to measure different aspects of a multi-dimensional construct?

________ is an approach for assessing the internal consistency of the set of items when several items are summated in order to form a total score for the scale.

In alternative-forms reliability,the same respondents are measured at two different times with an equivalent scale form being administered each time.

The number of scale categories used in noncomparative itemized scales is fixed at five.

Discuss construct validity and the types of construct validity.

A noncomparative scale is one of two scaling techniques in which each stimulus object is scaled independent of the other objects in the stimulus set.

Which scale is not an itemized rating scale (Table 9.1 in the text)?

________ is the extent to which differences in observed scale scores reflect true differences among objects on the characteristics being measured,rather than systematic or random errors.

________ is not constant.It represents transient factors that affect the observed score in different ways each time the measurement is made,such as transient personal or situational factors.
