Reliability is the degree to which measurement scores are free from random error, or error that comes from unknown sources. Reliability may be measured by using parallel forms of tests; test-retest, which measures the same objects at different times; internal consistency, based on a comparison of two halves of the same data; and inter-rater reliability, determined by the degree of agreement between two or more raters of the data.
