Description: We present a data set containing 705 between-study heterogeneity estimates as reported in 61 articles published in Psychological Bulletin from 1990-2013. The data set also includes information about the number and type of effect sizes, the Q-statistic, and publication bias. The data set is stored in the Open Science Framework repository and can be used for several purposes: (1) to compare a specific heterogeneity estimate to the distribution of between-study heterogeneity estimates in psychology; (2) to construct an informed prior distribution for the between-study heterogeneity in psychology; (3) to obtain realistic population values for Monte Carlo simulations investigating the performance of meta-analytic methods.
