One Sample KolmogorovSmirnov Test in SPSS YouTube
The Kolmogorov-Smirnov test is a nonparametric goodness-of-fit test and is used to determine wether two distributions differ, or whether an underlying probability distribution differes from a hypothesized distribution. It is used when we have two samples coming from two populations that can be different. Unlike the Mann-Whitney test and the Wilcoxon test where the goal is to detect the.

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.

Normality test in SPSS KolmogorovSmirnov ShapiroWilk Normality
The Kolmogorov-Smirnov test (KS Test) is a bit more complex and allows you to detect patterns you can't detect with a Student's T-Test. From Wikipedia: "The Kolmogorov-Smirnov statistic quantifies a distance between the empirical distribution function of the sample and the cumulative distribution function of the reference distribution.

The bottom line is that the Kolmogorov-Smirnov statistic makes sense, because as the sample size n approaches infinity, the empirical distribution function \(F_n (x)\) converges, with probability 1 and uniformly in x, to the theoretical distribution function \(F (x)\).Therefore, if there is, at any point x, a large difference between the empirical distribution \(F_n (x)\) and the hypothesized.

Kolmogorov Smirnov Two Samples Test using SPSS YouTube
The test statistic and corresponding p-value for each test are shown: Kolmogorov Smirnov Test: Test statistic: .113; p-value: .200; Shapiro-Wilk Test: Test statistic: .967; p-value: .699; The p-values for both tests are not less than 0.05, which means we do not have sufficient evidence to say the variable points is not normally distributed.

Conducting a KolmogorovSmirnov Normality Test (KS Test) in SPSS YouTube
The Shapiro-Wilk test examines if a variable is normally distributed in some population. Like so, the Shapiro-Wilk serves the exact same purpose as the Kolmogorov-Smirnov test. Some statisticians claim the latter is worse due to its lower statistical power. Others disagree.

Illustration of the Kolmogorov-Smirnov statistic. The red line is a model CDF, the blue line is an empirical CDF, and the black arrow is the KS statistic.. In statistics, the Kolmogorov-Smirnov test (K-S test or KS test) is a nonparametric test of the equality of continuous (or discontinuous, see Section 2.2), one-dimensional probability distributions that can be used to test whether a.

Testing for Normality of Distribution (the KolmogorovSmirnov test
The two well-known tests of normality, namely, the Kolmogorov-Smirnov test and the Shapiro-Wilk test are most widely used methods to test the normality of the data. Normality tests can be conducted in the statistical software "SPSS" (analyze → descriptive statistics → explore → plots → normality plots with tests).

so, formally, KS is inaccurate in this case. There is a version of KS test, called Lilliefors test, that tests normality of the distribution by comparing the data with a fitted normal distribution as we did above, but with a correction to give a more accurate approximation of the distribution of the test statistic. Example. (Lilliefors test.)

How to do Normal distribution tests in SPSS Kolmogorov Smirnov
SPSS runs two statistical tests of normality - Kolmogorov-Smirnov and Shapiro-Wilk. If the significance value is greater than the alpha value (we'll use .05 as our alpha value), then there is no reason to think that our data differs significantly from a normal distribution - i.e., we can reject the null hypothesis that it is non-normal.
