What is split-half reliability and what is gained by establishing this type of reliability?
What will be an ideal response?
Ans: Varies.
Split-half reliability is used to establish the internal consistency of a measure. The process involves dividing all of the items of a measure into two groups (e.g., first half and second half). For each participant, the research computes the score separately for each half of the items. Scores can then be correlated across all participants; scores that are highly correlated would suggest an internally consistent or internally reliable measure.
