Web3 de set. de 2024 · A third method of determining what is ‘normal’ is to look at the ‘median’ value of a distribution, that is the value which lies at the midpoint. In social statistics, it is very like that the median will provide a more representative average figure than the mean because a higher percentage of people will cluster around the median ... WebKolmogorov-Smirnov test in R. I tried to use the Kolmogorov-Smirnov test to test normality of a sample. This is a small simple example of what I do: One-sample Kolmogorov-Smirnov test data: x D = 0.3427, p-value < 2.2e-16 alternative hypothesis: two-sided. The p-value is very low whereas the test should accept the null-hypothesis.
