The scores are then compared to see if it is a reliable form of testing.
Example of parallel forms reliability. 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. This method has the advantage. Both forms are looked at to see if both are reliable or equivalent.
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. Group a takes test a first and group b takes test b first. Parallel forms reliability sometimes termed alternate forms reliability is one of the three primary classifications of psychometric reliability along with test-retest reliability and internal consistency reliability.
Can only detect less than 5000 charactersOccasions the test is producing coherent decisions. What is equivalent form of reliability. It can thus be viewed as being repeatability or consistency.
Parallel forms reliability is a measure of reliability obtained by administering different versions of an assessment tool both versions must contain items that probe the same construct skill knowledge base etc to the same group of individuals. You administer both instruments to the same sample of people. The scores from the two versions can then be correlated in order to evaluate the consistency of results across alternate versions.
A set of questions is formulated to measure financial. The results of the two tests are compared and the results are almost identical indicating high parallel forms reliability. Inter-rater reliability is a measure of reliability used to assess the degree to which different judges or raters agree in their assessment decisions.
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. Example of parallel forms reliability. We illustrate the computation and interpretation of parallel form reliability by another example due to Sprinthall.
