Average variance extracted Average variance extracted In statistics (classical test theory), average variance extracted (AVE) is a measure of the amount of variance that is captured by a construct in relation to the amount of variance due to measurement error. The average variance extracted was first proposed by Fornell & Larcker (1981). The average variance extracted can be calculated as follows: Here, formula_2 is the number of items, formula_3 the factor loading of item formula_4 and formula_5 the variance of the error of item formula_4. The average variance extracted has often been used to assess discriminant validity based on the following "rule of
