In Section 1.4.1 we calculated measures of center and location for the signal strengths at each location × angle × access point combination. (See for example Figure 1.9.) Another possible summary statistic we can calculate is the Kolmogorov-Smirnov test statistic for normality. If the signal strengths are roughly normal, then we expect the p-values to have a uniform distribution. This leads to about 5% of the p-values for the 8000 tests to fall below 0.05.
