How do you interpret skewness and kurtosis
WebIn this app, you can adjust the skewness, tailedness (kurtosis) and modality of data and you can see how the histogram and QQ plot change. Conversely, you can use it in a way that given the pattern of QQ plot, then check how the skewness etc should be. For further details, see the documentation therein. WebIn addition to skew, you can use kurtosis to get information about a data distribution. Skewness and kurtosis. Kurtosis is a way to describe the shape of the tails of a data distribution as compared to the centre. Kurtosis is a measurement of the tails of a data set, not of the peak of the data set! There are three main kinds of kurtosis.
