27	* Use a histogram to check for commn cause vs. special cause variation
28	* Use boxplots to explore differences by person
29	* Use a run chart to test trends over time. Subdivide each person's pulls.
30	* The Red Bead and Blue Bead Experiment work together to show the effects of reduced variability
