The F-ratio notation F(dfbetween, dfwithin) indicates the degrees of freedom between groups and within groups, respectively. The first number (3) plus 1 gives the number of groups (4), and the second number (20) represents the degrees of freedom within groups, which, when divided by the number of groups minus 1, gives the number of participants in each group (6).
