The following builds simulated data for a one-factor ANOVA, appropriate for a between subjects design. We build the data frame containg a column for the group factor levels, and a column for the DV. Then, we run the ANOVA an print it out.
Df | Sum Sq | Mean Sq | F value | Pr(>F) | |
---|---|---|---|---|---|
groups | 2 | 1187.127 | 593.5635 | 2.683555 | 0.0699765 |
Residuals | 297 | 65692.093 | 221.1855 | NA | NA |
In this next example, we simulate the same design 100 times, save the \(p\)-values, and the determine the proportion of significant simulations.
