Subclaims¶

q3 i? In the ToGRA regression the treatment group showed a mean gain of 0.379, statistically significant at P=<0.0001, controlling for gender, ethnicity and other categories. → Richardson 2013 q3 i? GATE participation was a significant positive covariate on both the NCGE (estimate 2.577, p=0.0025) and ToGRA (estimate 0.366, p=0.0010). → Richardson 2013 (2)

Evidence¶

Richardson 2013¶

q3 · i? · causal · r2

Regression analysis (Table 9) of ToGRA post scores on pre score, group and covariates for the 215-student sample. Only the group coefficient and its significance are printed; no standardized effect size is given for this regression, so impact is null.

"When controlling for all identified categories (gender, ethnic group, etc.), the treatment group showed a mean gain of 0.379. As shown in the last column, this is statistically significant at P= <0.0001."

Richardson 2013 (2)¶

From the NCGE regression table (Table 5), the GATE term carries estimate 2.577 with t ratio 3.062 and Prob>|t| 0.0025; the ToGRA regression (Table 9) shows GATE 0.366, p=0.0010. Hispanic, Asian and free-lunch terms were not significant in either model.
