A. One-way Analysis of Variance (ANOVA)

compute a simple analysis of variance in order to determine if there are significant group differences in BAI anxiety scores.

In the data set new variable called "GROUP" (new column) by doing the following:

The first 1-7 participants in the dataset should receive a value of "1" for GROUP

Participants 8-17 should receive a value of "2" for GROUP

Participants 18-25 should receive a value of "3" for GROUP.

Now that the groups variable is created we can evaluate if there are differences among the three groups that you just created using the procedure above in terms of the anxiety scores (BAI Score).
