A measure of the reliability of a test based on the correlation between equivalent forms of a test.

Example of equivalent forms reliability. Group A takes test A first and group B takes test B first. You administer both instruments to the same sample of people. Different people same time different test.

The parallel forms approach is very similar to the split-half reliability. Both groups take both tests. Process a given function is tested more than once over time and it is important to have more than one version of a given instrument and to show that these different versions are reasonably equivalent.

For example randomly split a 100-question test into Test A that contains 50 questions and Test B that also has 50 questions. The Insights Association. A measure of the reliability of a test based on the correlation between equivalent forms of a test.

One major problem with this approach is that you have to be able to generate lots of items that reflect the same construct. Parallel forms reliability also called equivalent forms reliability uses one set of questions divided into two equivalent sets forms where both sets contain questions that measure the same construct knowledge or skill. The consistency of results across alternate versions.

A measure of the reliability of a test based on the correlation between equivalent forms of a test. Parallel forms reliability also called equivalent forms reliability uses one set of questions divided into two equivalent sets forms. This can be examined by having groups of subjects take the two forms of the test to see if they do equally well on both.

In this method two parallel or equivalent forms of a test are used. What Is Market Research. 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.
