Testing Normality Using STATA 6. Testing Normality Using SPSS 7. Conclusion 1. Introduction Descriptive statistics provide important information about variables. Mean, median, and mode measure the central... Since a number of the most common statistical tests rely on the normality of a sample or population, it is often useful to test whether the underlying distribution is normal, or at least symmetric.

**Testing Normality StatMath Actualité**

The test is a modified version of a more sophisticated nonparametric goodness-of-fit statistical test called the Kolmogorov-Smirnov test. A feature of the Anderson-Darling test is that it returns a list of critical values rather than a single p-value.... Picking up the statement of Pearson (1930b) above, the following text discusses some tests designed to test formally the appropriateness or adequacy of the normal distribution as a model of the underlying phenomen from which data were generated.

## How To Write Up Kolmogorov Smirnov Tests Of Normality

This test is used in situations where a comparison has to be made between an observed sample distribution and theoretical distribution. K-S One Sample Test This test is used as a test of goodness of fit and is ideal when the size of the sample is small.

- An alternative test to the classic t-test is the Kolmogorov-Smirnov test for equality of distribution functions. In a simple example, we’ll see if the distribution of writing test scores across gender are equal using the High-School and Beyond 2000 data set.
