Internal Consistency
The degree of reliability within a test—the extent to which different parts of the same test yield the same results.
Split-Half Reliability
A measure of internal consistency, often ascertained by comparing responses on odd-numbered test items with responses on even-numbered test items and seeing if the scores for these responses are correlated.
Coefficient Alpha
A method for evaluating internal consistency, calculated by averaging the intercorrelations of all the items on a given test. The higher the coefficient alpha, the higher the internal consistency.
