The correlation between lineage and average sperm length for all 33 males was highly significant (r = -0.811, n = 33, t 31 = 7.71, p = 1.1E-8).
The correlation between lineage and average sperm length for all 33 males was highly significant (r = -0.811, n = 33, t 31 = 7.71, p = 1.1E-8).
While the value of +0.548 is marginally significant (p = 0.042), its evidence is far too weak to reject the null hypothesis of no correlation, given that the correlations for the other groups are both of opposite polarity (negative), and overall there is no significant correlation.
