Correlation between mean hybridization value and CV value in the repeated sequences. Correlation coefficients were computed for each individual species and for all species together. The upper part of the table details the mean and standard deviation of the correlation coefficients of 7736 repeated sequences in each case. It also specifies the number of sequences with a negative correlation between mean and CV. Lower part of the table details the t-test parameters. The scatter plot below illustrates the correlation between mean hybridization value and CV value in a sequence repeated in 5 different probesets. It shows that correlation exists when all species are considered together but that it does not hold for the individual species.
