The Winsorized mean is calculated as and the Winsorized sum of squared deviations is calculated as The Standard Error of the trimmed mean can then be calculated as WebbLevene’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. jimmy neutron peeing in the shower
