This dataset contains fake data from 2×2 factorial experiments with four treatment groups: Control (C), Factor A, Factor B, and the combination AB (A and B together). It includes means, standard deviations, and sample sizes for each group, as well as pre-computed effect sizes: log response ratio (lnRR), standardized mean difference (SMD), and their variances, for the main effects of A, B, and the interaction (AB).
