Fmax statistic

In statistics, Hartley's test, also known as the Fmax test or Hartley's Fmax, is used in the analysis of variance to verify that different groups have a similar variance, an assumption needed for other statistical tests. It was developed by H. O. Hartley, who published it in 1950. The test involves computing the ratio of the largest group variance, max(sj ) to the smallest group variance, min(sj ). The resulting ratio, Fmax, is then compared to a critical value from a table of t… WebLevene’s test works very simply: a larger variance means that -on average- the data values are “further away” from their mean. 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.
