  1. Note: For each of the four statistics (AD M(J) mean and r WG(J) mean for each scale), we obtained an empirical distribution based on 100,000 simulated random samples. The distributions are summarized in terms of their means, medians, standard deviations, and 5th and 95th percentiles. Consider the r WG(J) mean for the four-item Change Commitment scale. Its sample value was 0.82. Simulations under the uniform (rectangular) null distribution indicate that the empirical distribution has a mean of 0.20 and a 95th percentile of 0.33, which is much lower than the observed value of 0.82. Thus, the corresponding p-value is 0.00. Therefore, the conclusion is that based on the mean r WG(J) we reject the null hypothesis that there is no agreement in the ensemble of 10 INGOs.
