	Wild-type in PYE	Wild-type in PEG 35000	Δpilin in PYE	Δpilin in PEG 35000
Number of Switching Intervals	267	222	527	310
Average Interval (s)	0.81	0.74	0.76	0.73
Standard Error (s)	0.033	0.037	0.024	0.033
Standard Deviation (s)	0.52	0.55	0.55	0.57
Median (s)	0.64	0.59	0.61	0.57

Comparison of average switch intervals with standard errors, standard deviations, and median intervals, based on the number of measured intervals listed for wild-type and Δpilin cells in PYE with and without 4% PEG35000. Note the large values of the standard deviations due to the natural spread of switch intervals. Nevertheless, the average interval is nearly the same under all 4 conditions.
