Quantification of the difference between experimental distributions of FA properties. Cells were binned based on EGF concentration (no (0 nM), low (0.1 and 0.01 nM) and high (100, 10 and 1 nM)) or cell speed (low (<42 μm/hr) or high (>42 μm/hr)). The Kolmogorov-Smirnov statistic was the average of three pair-wise comparisons (EGF) or simply the pair-wise comparison (cell speed). A larger value for the Kolmogorov-Smirnov statistic signifies a higher probability that there are differences between groups.
