Whether offspring oriented to the predator or not was influenced by maternal predator-exposure treatment but not day of testing (covariate). Stickleback size and the 2-way interactions with the covariates were removed sequentially because the F-values were <1 and non-significant. D.f. approximated using containment, Pearson Chi-squared / d.f. = 0.97.
| Fixed effect | d.f. | F-value | P-value |
|---|---|---|---|
| Maternal treatment | 1, 15 | 8.84 | 0.009 |
| Day of testing | 1, 117 | 2.31 | 0.131 |
