Hello Barbara,
I dont completely understand what you are looking for or which non-parametric test you are looking to apply. Nemenyi), as described at
https://www. We can see that at each significance level, the test has found that the data follows a normal distributionThe D’Agostino’s $K^{2}$ test calculates summary statistics from the data, namely kurtosis and skewness, to determine if the data distribution departs from the normal distribution, named for Ralph D’Agostino. J. Running the above example calculates the statistic and p-value.

updates, webinars, and more!. H. If you are comparing several distributions, choose the one that gives the largest p-value; this is the closest match to your data. This sort of test can be used to check for normality, which is a common assumption in many statistical tests such as regression, ANOVA, and t-tests. g.

Instead, the p-value can be used to quickly and accurately interpret the statistic in practical applications. 092, you can be at least 99% confident that the data is normal. Small p-values (less than your chosen alpha level) means that you can reject the null hypothesis.
Unfortunately, the table values for the generic distribution is based on known values for a and b. To run a normality test using QI Macros: See how. Show lessUsing Cells D1:D41 (after deleting the blank row) from the XbarR.
