In contrast to scaling methods that employ indirect estimation,scaling methods that employ direct estimation do not require:
A) writing two sets of items for parallel forms.
B) the use of the method of equal-appearing intervals.
C) transforming testtaker responses into some other scale.
D) indirect methods to interpret testtaker responses.

Question

Quizplus · Accepted Answer

Direct scaling methods involve directly estimating the values of a construct, such as by using a ruler to measure length. Therefore, transforming testtaker responses into some other scale is not necessary. Choices A, B, and D are all examples of indirect scaling methods, which require some form of transformation or interpretation of testtaker responses.
