The data are plotted against a theoretical normal distribution in such a way that, if the data is normal, the points should form an approximate straight line.

Histograms break the range of values in classes, and display only the count or percent of the observations that fall into each class. Visual graphs, such as histograms, help one to easily see a few very important characteristics about the data, such as its overall pattern, striking deviations from that pattern, and its shape, center, and spread.Ī histogram is particularly useful when there is a large number of observations. When examining data, it is often best to create a graphical representation of the distribution.
