A normal probability plot is a graphical representation of a data set used to assess whether the data follows a normal (bell-shaped) distribution. When the option Q-Q plot is selected, the horizontal axis shows the z-scores of the observed values, z=(x−mean)/SD. Because the Normal family is a location-scale family, changing units makes no difference. A box and whisker plot shows the minimum value, first quartile, median, third quartile and maximum value of a data One can notice, however, that the two plots are a little different. For example, your numbers might be: As the observed quantiles of sample data follows the reference line, we conclude that the sample dataset follows a normal distribution.
