Test-Retest Reliability: Test-retest reliability assesses whether an intelligence test produces consistent results when individuals take it at two different points in time.
Split-half Reliability: Split-half reliability checks if there is internal consistency within an intelligence test by comparing one half of the items with another half.
Inter-rater Reliability: Inter-rater reliability examines whether multiple raters scoring the same intelligence tests achieve similar results, ensuring objectivity and consistency.
