Fig. 2

This figure shows the variances of unadjusted estimates computed using resampling with progressively reduced sample sizes, it visually represents the outcomes shown in Table 1. The coordinates (500, 0.0769) show the sample size and the variance of unadjusted estimates computed with the entire sample size of 500, and the coordinates (233.005, 0.1628) show the effective sample size and variance of the weighted analysis
