WebThe Ryan-Joiner statistic measures how well the data follow a normal distribution by calculating the correlation between your data and the normal scores of your data. If the correlation coefficient is near 1, the population is likely to be normal. This test is similar to the Shapiro-Wilk normality test. Interpretation. Web5.2.5 Testing for normality. Many statistical tests rely upon certain properties of the data. One common property, upon which many linear tests depend, is that of normality — the data must have been drawn from a normal distribution. It is necessary then to ensure normality before deciding upon the test procedure to use.
