Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

When researchers have subjects take two halves of a single test (split-half) or have them take the same test twice (test-retest), they are assessing the test’s ____

A	validity
B	reliability
C	standardization
D	factor analysis

Explanation:

Detailed explanation-1: -Parallel forms reliability measures the correlation between two equivalent versions of a test. You use it when you have two different assessment tools or sets of questions designed to measure the same thing.

Detailed explanation-2: -split-half method./split-half method This method establishes equivalence reliabilty by dividing the indicators of the same construct into two groups in order to determine whether they produce the same results.

Detailed explanation-3: -Split-half reliability is determined by dividing the total set of items (e.g., questions) relating to a construct of interest into halves (e.g., odd-numbered and even-numbered questions) and comparing the results obtained from the two subsets of items thus created.

Detailed explanation-4: -Test-retest reliability is a measure of reliability obtained by administering the same test twice over a period of time to a group of individuals. The scores from Time 1 and Time 2 can then be correlated in order to evaluate the test for stability over time.
