Do you know what a probability histogram is? A histogram is the representation of the distribution of numerical information. To create a histogram, the first thing you must do is divide the whole range of values into a sequence of intervals and then count how many values fall into each interval. The bins must be adjacent and equal in size. Taking this quiz to test drive your knowledge of histograms would be a learning experience, good luck.
