  1. The re-sample comparison gives the proportion of re-sampled 1-female colony brood weights with higher Shapiro-Wilk values than for 2, 3 or 4-female colonies. These proportions approximate the likelihood that a higher Shapiro-Wilk value could have been obtained from 1-female nests given the same sample size as for the multi-female colony size (see Methods).
