How do I run a Kolmogorov-Smirnov in SPSS?
In order to test for normality with Kolmogorov-Smirnov test or Shapiro-Wilk test you select analyze, Descriptive Statistics and Explore. After select the dependent variable you go to graph and select normality plot with test (continue and OK).
Where is Kolmogorov-Smirnov test in SPSS?
Figure 1: Selecting a Kolmogorov–Smirnov Test From the Analyze Menu in SPSS. In the dialog box that opens, move the variable, MCZ_3, to the Dependent List, as shown in Figure 2. Then click “Plots” on the right-hand corner of the dialog box. Figure 2: Selecting a Variable for Analysis.
How do I get Kolmogorov-Smirnov?
- Create an EDF for your sample data (see Empirical Distribution Function for steps),
- Specify a parent distribution (i.e. one that you want to compare your EDF to),
- Graph the two distributions together.
- Measure the greatest vertical distance between the two graphs.
- Calculate the test statistic.
Where do I use SPSS?
SPSS is used by market researchers, health researchers, survey companies, government entities, education researchers, marketing organizations, data miners, and many more for processing and analyzing survey data, such as you collect with an online survey platform like Alchemer.
What is the Kolmogorov-Smirnov test of normality?
The Kolmogorov-Smirnov test is used to test the null hypothesis that a set of data comes from a Normal distribution.
How do you interpret the p-value for Kolmogorov-Smirnov?
The p-value is the probability of obtaining a test statistic (such as the Kolmogorov-Smirnov statistic) that is at least as extreme as the value that is calculated from the sample, when the data are normal. Larger values for the Kolmogorov-Smirnov statistic indicate that the data do not follow the normal distribution.

What is a significant Kolmogorov-Smirnov test?
The Kolmogorov-Smirnov test (Chakravart, Laha, and Roy, 1967) is used to decide if a sample comes from a population with a specific distribution. An attractive feature of this test is that the distribution of the K-S test statistic itself does not depend on the underlying cumulative distribution function being tested.
