Parallel forms reliability example Both groups take both tests.
Example of parallel forms reliability. We illustrate the computation and interpretation of parallel form reliability by another example due to sprinthall. 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. You administer both. The results of the two tests are compared and the results are almost identical indicating high parallel forms reliability.
Parallel forms reliability example a set of questions is formulated to measure financial risk aversion in a group of respondents. The scores from the two versions can then be correlated in order to evaluate the consistency of results across alternate versions. 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.
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. As a measurement model for the scores of parallel forms strict parallel measures are assumed so that the correlation between the scores ie the parallel-forms reliability or parallel-test reliability matches the reliability of both forms. 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.
A measure of the reliability of a test based on the correlation between equivalent forms of a test. This method has the advantage. For example if the professor gives out test A to all students at the beginning of the semester and then gives out the same test A at the end of the semester the students may simply memorize the questions and answers from the first test.
What is equivalent form of reliability. It can thus be viewed as being repeatability or consistency. Both forms are looked at to see if both are reliable or equivalent.
