To begin to understand what a standard deviation is, consider the two histograms. The following histogram shows the personal income of a large sample of individuals drawn from U.S. census data in the year 2000. The normal distribution is the familiar bell shaped curve shown in the above figure. As a second example, we will create 10000 random deviates drawn from a Gaussian distribution of mean 8.0 and standard deviation 1.3.When we plot the histogram of these 10000 random points, we should get back an approximately bell shaped Gaussian curve.
