FIG. 2.

Summary of the FPR results examined in Eklund and associates (2016), combining all their test results (available from their GitHub repository). The results of each software across all voxelwise p = 0.01 and p = 0.001 cases are shown separately. Red lines show the median; the box covers the 25–75% interquartile range; whiskers extend to the most extreme data point within 1.5 × the interquartile range; and outliers are shown as dots. For a given voxelwise p, results are similar across parametric methods, with typical ranges of 15–30% FPR for p = 0.01 and 5–15% FPR for p = 0.001.
