Figure B2: Visualization of Monte Carlo simulations investigating how sample size affects estimates of variation. Panels A and B display samples of simulations using observed means and standard deviation observed for maxillary head height and head depth in our dataset. The red line in each panel represents the mean trait value at each sample size. The black ribbons show the minimum and maximum trait value at each sample size, and the blue ribbons show the standard deviation around the mean at each sample size. The vertical line in each graph indicates where increasing sample size no longer significantly impacts estimates of standard deviation (i.e., where estimates of variation stabilize). Panel C shows histograms of the sample sizes associated with stabilization across traits.
