Even by chance this will sometimes not be the case.

Example of equivalent forms reliability. Different people same time different test. Example of equivalent forms reliability. Science and technology Psychology.

For example randomly split a 100-question test into Test A that contains 50 questions and Test B that also has 50 questions. Group A takes test A first and group B takes test B first. Scores are obtained from the same group of people but the scores are taken from different forms of a test.

Equivalent-forms reliability is established in a manner similar to test-retest. The parallel forms approach is very similar to the split-half reliability. According to equivalent reliability method the reliability R NS should be equal to the planned design reliability R Sie left1-frac1Trightt_0prod limits_tt_01LFleftx_TNStheta_trightleft1-frac1TrightL.

Alternate form reliability occurs when an individual participating in a research or testing scenario is given two different versions of the same test at different times. A measure of the reliability of a test based on the correlation between equivalent forms of a test. The different forms of the test or instrument are designed to measure the same thing the same construct.

The process for calculating parallel forms reliability is as follows. In this method two parallel or equivalent forms of a test are used. A measure of the reliability of a test based on the correlation between equivalent forms of a test.

Estimating reliability by means of the equivalent form method involves the use of two different but equivalent forms of the test. The correlation between the two parallel forms is the estimate of reliability. Alternate form reliability definition alleydog alternate.
