Suppose you gave a skill test to 3 different PE classes and want to know if they differ in terms of their scores. The skill tests scores are as follows:

Class 1: 23, 21, 19, 22

Class 2: 18, 19, 21, 18

Class 3: 21, 20, 19, 22

Conduct an ANOVA and report the test statistic rounded to 2 decimal places.
