Answer to Question 1

ANS: D
Tests of instrument internal consistency or homogeneity, used primarily with paper-and-pencil tests or scales, address the correlation of various items within the instrument. The original approach to determining internal consistency was split-half reliability. This strategy was a way of obtaining test-retest reliability without administering the test twice.

Answer to Question 2

ANS: A
Equivalence reliability compares two versions of the same paper-and-pencil instrument or two observers measuring the same event. Determining interrater reliability is a concern when studies include observational measurement, which is common in qualitative research. Interrater reliability values need to be reported in any study in which observational data are collected or judgments are made by two or more data gatherers. Consequently, it is used in various types of qualitative research in which data or behaviors are coded.
