It works by plotting the two cumulative distribution functions against each other; if they are similar, the data will appear to be …

Webb15 apr. 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. If the bottom end of the Q-Q plot deviates ...
