The following code shows how to perform a Shapiro-Wilk test on a dataset with sample size n=100: The p-value of the test turns out to be 0.6303. Since this value is not less than .05, we can assume the sample data comes from a population that is normally distributed.

Webb8 aug. 2024 · We can develop a QQ plot in Python using the qqplot () statsmodels function. The function takes the data sample and by default assumes we are comparing it to a Gaussian distribution. We can draw the standardized line by setting the ‘ line ‘ argument to ‘ s ‘.

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. black sheep quilt store
