In Module 3 of our 10-week, Free Online Psychometric Testing Course, we consider the topic of Psychometric Test Reliability. This Module will be released on 21 October, 2015 to those registered for our Psychometrics MOOC. Below is an outline of what is to be covered.
Summary of Module 3: Psychometric Test Reliability
So far, we understand what a psychometric test is. We also have learned how important it is to consider the role requirements, and thus know what we need to assess before even starting to research which psychometric tests are available to us.
In this Module, we now start to look at the major technical properties of psychometric tests. The particular property introduced in this Module is reliability. This tells us about whether a test is making consistent measurements of whatever it is supposed to measure. In the Module, we take this definition further and explain what to look out for in terms of test reliability, and what the different types of reliability mean.
Towards the end of the Module we will go through some test manuals, looking for and evaluating evidence for test reliability.
