q2 · i? · causal · r2

Baseline descriptive comparison of the 59 teachers (Table 1: 19 African American / 11 White in intervention; 2 African American / 26 White in control). The article reports no other statistically significant pre-intervention differences between the groups.

"Chi-square tests and t-tests used to compare the descriptive information determined that the control teachers only differed from the experimental teachers in race. There were more African American teachers in the group that received the intervention and more white teachers in the control group."
