Shapiro - Wilk's test for normality
------------------------------------------------------------------------------
D = 0.009
W = 0.915
Critical W (P = 0.05) (n = 24) = 0.916
Critical W (P = 0.01) (n = 24) = 0.884
------------------------------------------------------------------------------
Data PASS normality test at P=0.01 level. Continue analysis.

Hartley's test for homogeneity of variance
Bartlett's test for homogeneity of variance
These two tests can not be performed because at least one group has
zero variance.
Data FAIL to meet homogeneity of variance assumption.
Additional transformations are useless.
