Table 2.

Post-hoc comparison using 2-sample t-tests show that autocorrelation period runs longer under constant light (LL) than when photoentrained (LD1) or under constant darkness (DD) for each EOD variable and for the mean of all three variables

Two-tailed alpha of 0.05, when corrected for 8 comparisons is 0.0063 (* significant in table). Neither sex nor experiment were significant in multiway ANOVA, so period data are pooled across both terms.
