Subclaims

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q2 i? Pretest-posttest correlation coefficients for state assessment data differ across samples of low-performing, average-performing, and proficient students. → Russell Cole 2011

The report's stated purpose, from its abstract: an examination of variability in pretest-posttest correlations for state assessment data across achievement-level samples, "to determine how sample characteristics (such as achievement level) affect pretest-posttest correlation coefficients." No effect sizes are printed on the available page.

"This report examines variability in pretest-posttest correlation coefficients for state assessment data on samples of low-performing, average-performing, and proficient students to determine how sample characteristics (such as achievement level) affect pretest-posttest correlation coefficients."
