The pre-workshop group had a mean of 3.3 for their rating on excitement for STEM compared to the post-workshop group's mean of 2.0. The median for each of the groups were 3.0 and 1.0, respectively.
This shift in the mean and median shows promising results on the efficacy of these workshops in increasing students' excitement for STEM. |
To the left is the distribution of the survey pre- and post- activity. As shown, the distribution of the pre-workshop had a wider range and more skewed to the right than the post-workshop group.
The distribution shift suggests that the activity had students more excited about STEM. Many of them, in fact, mentioned how they'd like their STEM classroom to be more interactive. The result can also be visualized in the boxplot below. |
