Question
How is the F-statistic in an ANOVA test calculated?a.)The variance between the samples minus the variance within the samplesb.)The variance between the samples plus the variance within the samplesc.)The variance between the samples divided by the variance within the samplesd.)The variance between the samples multiplied by the variance within the samples
Solution
The F-statistic in an ANOVA test is calculated as follows:
c.) The variance between the samples divided by the variance within the samples
This is done to compare the amount of variation between different groups to the amount of variation within the groups. If the variance between groups is significantly larger than the variance within groups, it suggests that the groups are different from each other.
