WebbThere are two methods of plotting the Bivariate Normal Distribution. One method is to plot a 3D graph and the other method is to plot a contour graph. A contour graph is a way of displaying 3 dimensions on a 2D plot. A 3D plot is sometimes difficult to visualise properly. WebbOne way to represent the population distribution of data values is in a histogram, as described in Section 1.1. The difference now is that the histogram displays the whole population rather than just the sample. Since the population is so much larger than the sample, the bins of the histogram (the consecutive ranges of the data that comprise ... 3雷灵
