Question

Quizplus · Accepted Answer

Parallel forms, split half, and item-total are all tests for reliability, which refers to the consistency and stability of a measurement tool. Parallel forms involve administering two different versions of the same test to the same group of participants to assess if the two forms yield similar scores. Split half involves dividing a test into two halves and comparing the scores of each half to assess if they are consistent. Item-total involves comparing the scores of individual items on a test to the total score of the test to assess if each item is contributing to the overall measurement in a consistent manner.
