Example Of Parallel Forms Reliability
Same people different times.
Example of parallel forms reliability. In parallel forms reliability you first have to create two parallel forms. B you want to evaluate the degree to which the art portfolios in your 7th grade class meets the required standards. Parallel forms of a test are different subsets of the same universe of items which capture the same attribute with the same accuracy.
The two sets of questions are given to the same sample of people within a short period of time and an estimate of reliability is calculated from the two sets. Different people same time different test. Group a takes test a first and group b takes test b first.
You administer both instruments to the same sample of people. We illustrate the computation and interpretation of parallel form reliability by another example due to sprinthall. The two tests should then be administered to the same subjects at the same time.
This is accomplished by creating a large pool of test items that measure the same quality and then randomly dividing the items into two separate tests. Parellel forms reliability is gauged by comparing to different tests that were created using the same content. 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.
This is an example of parallel forms reliability because two different forms of the same assessment are being evaluated. The consistency of results across alternate versions. The correlation between the two parallel forms is the estimate of reliability.
Different people same test. Reliability of any research is the degree to which it gives an accurate score across a range of measurement. As a measurement model for the scores of parallel forms strict parallel measures are assumed so that the correlation between the scores i e the parallel forms reliability or parallel test reliability matches the reliability of both forms.
