Summary

Suppose you want to investigate the health status of some students. You collect 40 students and record the name, gender, age, height and weight of each observation. After collecting your data, you would like to examine if the weights of students follow a normal distribution, so you use Normality Test procedure.

Operation

1. Import body.dat on the \Samples\Statistics folder.
2. Highlight Column E
3. Select Statistics: Descriptive Statistics: Normality Test
4. Check All of the tests on Quantities to Compute branch.
5. Select Histograms and Box Chart in Plots branch.
6. Click OK

Interpreting the results

All the test results indicate that the data follows a normal distribution, because the p-values are greater than 0.05 for the tests. Moreover, the box chart and the histogram also give an intuitive sense that the data is normally distributed.
