In statistics parallel forms reliability measures the correlation between two equivalent forms of a test.
Example of equivalent forms reliability. Furthermore this approach makes the assumption that the randomly divided halves are parallel or equivalent. Different people same time different test. Equivalent-forms reliability is established in a manner similar to test-retest.
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. A measure of the reliability of a test based on the correlation between equivalent forms of a test. A measure of the reliability of a test based on the correlation between equivalent forms of a test.
Reliability for teachers activity what are the three types of reliability. Equivalent forms reliability is a term used in psychometrics the measurement of intelligence skills aptitudes etc to determine whether or not two or more forms of tests that are designed to measure some aspect of mentality are truly equivalent to one another.

Science and technology Psychology. The questions are randomly divided into two sets and the respondents are randomly divided into two groups. The consistency of results across alternate versions.
The Insights Association. It is not enough to simply rearrange the item order. In this method two parallel or equivalent forms of a test are used.
The forms should be as similar as possible but use different questions or wording. The parallel forms approach is very similar to the split-half reliability. The different forms of the test or instrument are designed to measure the same thing the same construct.
