Video: Reliability, Precision, and Measurement in the Context of Data from Ability Tests, Surveys
William P. Fisher, Jr. - Berkeley University California
Reliability tends to increase with sample size and test length, as error decreases relative to variation.
Reliability is affected by the internal consistency of the data, but not as much as it is by sample size and test length.
Internal consistency must be evaluated by means of different approaches attuned to different types of failures of invariance.
