To assess the statistical significance of an obtained f value, it must be compared with a critical f value. The critical f value is determined using two pieces of information: sample size and the number of groups. This comparison helps to establish whether the results are significant.

1. To determine whether an obtained F value is statistically significant, it must be compared to a
critical F value. What two pieces of information are needed to determine the critical F value?
Mean and sample standard deviation Expected frequency and obtained frequency Sample size
and number of groups
