## Usage Note *35406: *How do I interpret the Shapiro-Wilk test for normality in JMP®?

The Shapiro Wilkes test for normality is available when using the Distribution platform to examine a continuous variable.

The null hypothesis for this test is that the data are normally distributed. The Prob < W value listed in the output is the p-value. If the chosen alpha level is 0.05 and the p-value is less than 0.05, then the null hypothesis that the data are normally distributed is rejected. If the p-value is greater than 0.05, then the null hypothesis is not rejected.

Additional information about assessing normality of data can be found in the JMP Learning Library. Select the category Probabilities and Distributions.
