![]() There you will find out that we cannot calculate reliability - we can only estimate it.īecause of this, there a variety of different types of reliability that each have multiple ways to estimate reliability for that type. With this foundation, you can consider the basic theory of reliability, including a precise definition of reliability. First, you have to learn about the foundation of reliability, the true score theory of measurement.Īlong with that, you need to understand the different types of measurement error because errors in measures play a key role in degrading reliability. Before we can define reliability precisely we have to lay the groundwork. In its everyday sense, reliability is the "consistency" or "repeatability" of your measures. Reliability has to do with the quality of measurement.
