q3 i? Class size correlates negatively with mean note size (r=-0.59, p<0.01), and the correlation remains significant after removing two outliers (r=-0.55, p<0.01). → Hewitt 2007

Correlational analysis of note sizes in the 28-course log dataset, reported in Fig. 3. The article reports a significant negative correlation (r=-0.55, p<0.01) after removing two outlier points, indicating "students tended to write shorter notes as the class size increased".

"A comparison of class size and size of notes (Fig. 3) revealed a negative correlation between size of class and the mean size of notes (r=-0.59, p<0.01). This suggests that students tended to write shorter notes as the class size increased."
