  • a The P value from the Fisher exact test was found to be 0.001, implying that statistically significant differences exist in the frequency of observing towers as a function of applied shear stress. Comparisons of the six other shear stress levels against the level of 0.6 dynes/cm2 with and without the Benjamini Hochberg adjustment are shown.
