Alternate-form reliability is the consistency of test results between two different but equivalent forms of a test.

Example of alternate forms reliability. This is an example of parallel forms reliability the consistency of results across alternate versions. Validity of the research is defined as the precision of scale and data collection. This is sometimes known as the coefficient of equivalence.

Evidence for moderate alternate form reliability for the ELF r 61 was found by Bryan et al. Parallel forms reliability is often used in academic settings when a professor doesnt want students to be able to have access to test questions in advance. 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.

The questions are randomly divided into two sets and the respondents are randomly divided into two groups. The scores are then compared to see if it is a reliable form of testing. If the scores differ dramatically.

An individual is given one form of the test and after a period of time usually a week or so the person is given a different version of the same test. The resulting coefficient is called the alternate-form. Group A takes test A first and group B takes test B first.

Reliability and Validity in Measurement. Alternate forms reliability means that two different versions of the same formtest should produce similar responses from the individuals being tested. To determine alternate form reliability two forms of the same test are administered to students and students scores are correlated on the two test forms.

A set of questions is formulated to measure financial risk aversion in a group of respondents. B You want to evaluate the degree to which the art portfolios in your 7th grade class meets the required standards. 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.
