The one-sample Kolmogorov-Smirnov (KS) test is used to determine whether a sample comes from a specific distribution. It is particularly useful when the assumption of normality is in question or when dealing with small sample sizes. The test statistic, denoted as , measures the maximum difference between the two cumulative distribution functions.

If the data are normally distributed, we use parametric tests. If data are not normally distributed, we use nonparametric tests. We can also use plots to assess data distribution. We use the Shapiro-Wilk test when we have a small sample size (N smaller than 50) and Kolmogorov-Smirnov test when we have a large sample size (N greater than 50).

How to Report P-Value of Kolmogorov-Smirnov and Shapiro-Wilk tests of normality Table in SPSS Output? The third table shows the results of Kolmogorov-Smirnov and Shapiro-Wilk tests of normality (tests statistic, degrees of freedom, p-value). Since we have less than 50 observations (N = 32 < 50), we will interpret the Shapiro-Wilk test results.

From the Kolmogorov-Smirnov Table we see that. Dn,α = D1000,.05 = 1.36 / SQRT (1000) = 0.043007. Since Dn = 0.0117 < 0.043007 = Dn,α, we conclude that the data is a good fit for the normal distribution. Example (Raw Data) Example 2: Using the KS test, determine whether the data in Example 1 of Graphical Tests for Normality and Symmetry is.

The Kolmogorov-Smirnov test uses the maximal absolute difference between these curves as its test statistic denoted by D. In this chart, the maximal absolute difference D is (0.48 - 0.41 =) 0.07 and it occurs at a reaction time of 960 milliseconds. Keep in mind that D = 0.07 as we'll encounter it in our SPSS output in a minute.

How to test normality with the KolmogorovSmirnov Using SPSS SPSS Tests
A Normal Distribution Test, as the name implies, is a statistical method employed to determine if a dataset follows a normal distribution. The assumption of normality is fundamental in various statistical analyses, such as t-tests and ANOVA. In the context of SPSS, researchers utilize tests like the Kolmogorov-Smirnov test and Shapiro-Wilk test.
SPSS Kolmogorovsmirnov Analysis
The "goodness-of-fit test" that we'll learn about was developed by two probabilists, Andrey Kolmogorov and Vladimir Smirnov, and hence the name of this lesson. In the process of learning about the test, we'll: learn a formal definition of an empirical distribution function. justify, but not derive, the Kolmogorov-Smirnov test statistic.
