Solved What is a normal probability plot and how is it used . . . - Chegg A normal probability plot is a stem-and-leaf plot with a matching normal probability distribution drawn on it It can be used to check normality because the shape of the stem-and-leaf plot will closely match the normal distribution if the data are approximately normal
