Fmax statistic

WebApr 23, 2014 at 19:59. 1. What you have there is a table of critical values. It only gives tail areas up to 10%; you can use properties of the F to find lower tail values, but the biggest one-tailed p-value you can get from that set of tables will be 10%. All you'd be able to say is ">0.1" rather than "=0.1538". 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…

If the p-value that corresponds to the test statistic is less than some significance level (like α = 0.05) then we can reject the null hypothesis and conclude that not all groups have the same variance. Example: Bartlett’s Test

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.
