Question

A 7th grade science teacher would like to know if spending more time doing class experiments will help his students preform better on tests. In a day, he teaches 4 periods of science, so for his 1st and 3rd period classes, he taught as he normally does with mostly lectures and occassional class experiments. For his 2nd and 4th period classes, he did a class experiment everyday with minimal lectures. There were n=25 different students in each of his classes. He then wanted to compare the exam averages between his classes to see if student preformance was significantly different. Which statistical tests should he use?
