WebTesting for homogeneity of variance with Hartley's Fmax test: In order to use a parametric statistical test, your data should show homogeneity of variance: in other words, the spread of scores in each condition should be roughly similar.(The spread of scores is reflected in the variance, which is simply the standard deviation squared).

The figure below illustrates this: watch the histograms become “wider” as the variances increase. We therefore compute the absolute differences between all scores and their (group) means.
