WebbIn statistics, explained variationmeasures the proportion to which a mathematical model accounts for the variation (dispersion) of a given data set. Often, variation is quantified as variance; then, the more specific term explained variancecan be used. The complementary part of the total variation is called unexplainedor residualvariation. Webb23 apr. 2024 · As in a one-factor design, η2 is the proportion of the total variation explained by a variable. Partial η2 for Age is SSQAge divided by ( SSQAge + SSQerror ), which is 1440 / 2340 = 0.615. As you can see, the partial η2 is larger than η2.
