VWB23_pilot

Data from a meta-analysis on the effects of collaborative models
of instruction on student achievement from Vembye, Weiss, and
Bhat (2023).

datasets

Provides functions to compute and plot power levels, minimum detectable effect sizes, and minimum required sample sizes for the test of the overall average effect size in meta-analysis of dependent effect sizes.
