IOP3701 Assignment 3 Due September 2024
In a recruitment context, if Lerato uses the same cognitive test multiple times, a reliable test would produce similar results for a candidate across different testing sessions (assuming no significant changes in the candidate’s abilities). Reliable measures are essential for making accurate and fair selection decisions.
Types of Reliability Relevant to Cognitive Functioning Tests
Test-Retest Reliability
This refers to the stability of test scores over time. It is measured by administering the same test to the same group of individuals on two separate occasions and then calculating the correlation between the two sets of scores. If Lerato administers a cognitive ability test on two different days to the same candidates, the test-retest reliability coefficient will show how consistent the results are across time. A high correlation would indicate stability and reliability.
Alternate-Form Reliability
This measures the consistency of results between two equivalent versions of the test. Different versions of the test are administered to the same group of people, and the correlation between the scores is ……
