Notes. Each data point is the mean of 1,000 repetitions with the outcome being arcsine transformed Cramer's V. Parameters for number of observations and conditional probability are adjusted for interpretability; N refers to number of simulations run. Simulations for sample size n = 20 were not included in this analysis because these simulations did not produce interpretable results with two of the methods.
