ANOVA Table
The one-way ANOVA table organizes the sums of squares, degrees of freedom, mean squares, and the $F$ statistic:
| Source | df | Sum of Squares | Mean Square | Statistic |
|---|---|---|---|---|
| Between treatments | $k-1$ | $SSTreat$ | $MSTreat$ | $F = MSTreat / MSE$ |
| Within treatments | $N-k$ | $SSE$ | $MSE$ | |
| Total | $N-1$ | $SST$ |
This table is the standard summary output for one-way ANOVA.

fit <- aov(y ~ treatment, data = dat)
