The airport limousine example in Chapter 2 illustrates how important the knowledge of random distribution of data and the shape of the histogram can be to drawing statistically sound conclusions. Although we didn’t state it in the example, the assumption that the data followed a known statistical distribution was inherent in the calculations of the three contour radii based on the standard deviation of the data values. In this chapter, we present the technique of fitting a statistical model to a set of observed data and testing for “goodness of fit.”
