The Transformation of Counts of European Chafer Larvae for Analysis of Variance1

Abstract
The mean and variance of groups of counts of 3rd instar (Amphimallon majalis) larvae in foot-square sampling-units, each group consisting of 25 units, were calculated for each of 3 locations. Data from the calculations indicated that the variance of each group was dependent upon the mean in a linear relationship. When the value of each count was transformed to [square root]x ?+ 1/2 there was no significant correlation between the mean and the variance.
