Answer 1

Which of the following sources of variability is guaranteed to exist in a study?

  Between-Group   

The sources of variation in the data are the variability that occurs within a sample group and the variability that occurs between the groups

As a researcher using ANOVA, in order to reject the null hypothesis, we need the F ratio to be:

greater than 1

In order to reject the null hypothesis that the group means are equal, we need a high F-value.
