Optional Activity 4

1. Yes, the students improved from pre- to post-test. Since mean difference 7.2 > 0, the post-test values are higher than the pre-test values

2.
H0: there are no gender differences in post-test scores
H1: there are gender differences in post-test scores

Based on p-value = 0.1164 > 0.05, fail to reject H0. Conclude that there are no gender differences in post-test scores

4. Group Study-Flashcards: p-value = 0.8839584 > 0.05
Reading Only-Flashcards: p-value = 0.0072325 < 0.05
Reading Only-Group Study: p-value = 0.0178850 < 0.05

This suggests that Group Study-Flashcards outweighs Reading Only-Flashcards and Reading Only-Group

5. the Tukey post hoc test would be useful in designing student support strategies, since it can accurately show what methods work, given the data
