Quizplus · Accepted Answer

When one-way ANOVA is performed, the F-statistic is used to determine whether there is a significant difference between the means of the groups being compared. F-value is calculated by dividing the variance between the groups by the variance within the groups. When the null hypothesis is rejected, it means that there is a significant difference between at least one of the groups being compared. In this case, the F-value should be greater than 1. Therefore, the correct choice is C (>1). Choices A and B are incorrect because an F-value of 0 or 1 indicates that there is no difference between the groups being compared. The choice D is incorrect because an F-value less than 1 indicates that the variance within the groups is greater than the variance between the groups, which means that there is no significant difference between the means of the groups.
