Webb28 feb. 2024 · Q-Q plots are also used to find the skewness (a measure of asymmetry) of a distribution. When we plot theoretical quantiles on the x-axis and the sample quantiles whose distribution we want to know on the y-axis, then we see a very peculiar shape of a normally distributed Q-Q plot for skewness. Webb16 maj 2024 · H 0: The sample data follow the hypothesized distribution. H 1 : The sample data do not follow the hypothesized distribution. For goodness-of-fit tests, small p-values indicate that you can reject the null hypothesis and conclude that your data were not drawn from a population with the specified distribution.
