Normal probability plot in spss

WebStatistical software sometimes provides normality tests to complement the visual assessment available in a normal probability plot (we'll revisit normality tests in Lesson 6). Let's take a look at examples of the different kinds of normal probability plots we can obtain and learn what each tells us. Normally distributed residuals WebDefinition. The normal probability plot is formed by plotting the sorted data vs. an approximation to the means or medians of the corresponding order statistics; see rankit.Some plot the data on the vertical axis; others plot the data on the horizontal axis. Different sources use slightly different approximations for rankits.The formula used by …
