Example Of Equivalent Forms Reliability

A test is given and divided into halves that are scored separately o results of one half of the test are then compared with the results of the other if the items get progressively more difficult then you might be better advised to use the odd even system.

Example of equivalent forms reliability. Parallel forms reliability example a set of questions is formulated to measure financial risk aversion in a group of respondents. A measure of the reliability of a test based on the correlation between equivalent forms of a test. Both groups take both tests.

Test retest measures consistency from one time to the next. Test retest equivalent form and internal consistency. Where one subscore is.

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. In parallel forms reliability you first have to create two parallel forms. You administer both instruments to the same sample of people.

There are three major categories of reliability for most instruments. 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. Also called parallel form reliability.

In psychology the consistency of measurement based on the correlation between scores on two similar forms of the same test taken by the same subject. An individual is given one form of the test and after a period of time. The questions are randomly divided into two sets and the respondents are randomly divided into two groups.

This can be examined by having groups of subjects take the two forms of the test to. The scores are then compared to see if it is a reliable form of testing. Each measures consistency a bit differently and a given instrument need not meet the requirements of each.
