Table 4.
A two-way ANOVA on the relative productivity per female with location and temperature as fixed effects.
| Source of variation | df | MS | F |
| Location+ | 1 | 0 | 0 |
| Temperature | 3 | 0.255 | 290 *** |
| Location X temperature | 3 | 0.00623 | 7.08 ** |
| Residuals | 12 | 0.00088 |
+ The between Location variance is 0 as we imposed the same productivity to each population.
**P < 0.01; ***P < 0.001; df, degree of freedom; MS, mean square; F, variance ratio.
