The notation F(3,36) in a one-way ANOVA result indicates that there are 3 degrees of freedom between groups, which corresponds to 4 groups (since degrees of freedom are calculated as the number of groups minus 1), and 36 degrees of freedom within groups, which corresponds to the total number of participants minus the number of groups (40 participants - 4 groups = 36). Therefore, there were 4 groups and 40 participants in total.
