Subclaims¶

q3 i3 Pearson correlations between pre- and post-test scores were r=0.63 (p<0.01) for the whole sample and r=0.63 (p<0.01) for the middle school subsample, with a reported very strong relationship for the high school sample (r=0.95, p=0.08). → Corlu 2011

q3 · i3 · causal · r2

Correlational analysis within the same quasi-experiment: "a correlation between pre- and post-test scores for the whole sample (r=0.63, p<0.01)" and the same for middle school; the high school correlation (r=0.95) was not statistically significant (p=0.08). These correlations fed into the effect size calculation.

"there was a correlation between pre- and post-test scores for the whole sample (r=0.63, p<0.01), as well as for middle (r=0.63, p<0.01) and a very strong relationship for the high school sample (r=0.95, p=0.08)"
