Question

A personality researcher administered her new measure of self-esteem to a group of participants. She waited two weeks and then gave the test to the same people again. She found that scores on the test changed quite a bit during the two-week period. Many participants who had scored low during the first administration scored high the second time, and many who had scored high initially scored low on the second administration. What problem does the researcher have with the new test

Answer 1

poor test-retest reliability

Step-by-step explanation:

Test-retest reliability: In research, the term "test-retest reliability" is also referred to as "retest reliability" and tends to measure test consistency. In "test-retest reliability", the reliability of a specific test is being measured over a while.

In other words, a researcher tends to give a similar test twice to the same subjects or participants at different times to analyze if the test results are the same.

Example: A specific test is given on Wednesday, then again on the following Wednesday.

In the question above, the given statement represents "poor test-retest reliability".
