Study Notes
Types of Reliability
-
Internal consistency reliability: Measures the degree of consistency of results across items within a single test, ensuring all items assess the same construct.
-
Interrater reliability: Evaluates the level of agreement between different raters or observers; high interrater reliability indicates that different evaluators reach similar conclusions about the same data.
-
Parallel forms reliability: Involves administering different but equivalent versions of a test to the same group; aims to verify that various forms yield consistent results for the same construct.
-
Split-half reliability: Assesses the consistency between two halves of a test, where each half should yield similar scores from the same subjects, indicating internal consistency.
-
Test-retest reliability: Involves giving the same test to the same subjects at different points in time; high correlation between scores suggests stability and consistency of the test over time.
