WebThere are four main central moments: 1. First central moment (mean): The first central moment is the average of all the data points in a set. It gives us an idea of the center of the distribution. 2. Second central moment (variance): The second central moment is the average of the squared deviations of each data point from the mean. WebAnswer only. Step 1/2. Kurtosis is the measurement of peakedness of distribution. It will generally reflect the long tails or short tails or medium tails and it will reflect the peakedness of probability distribution. It will exhibit the combine weight of tails of distribution and how they are different from normal distribution.

WebObviously, the kurtosis of the distribution during displacement process is greater than zero, so the peakedness is steep. However, the kurtosis under static condition is less than zero, so the peakedness is gentle. There are positive and negative skewness values, so the asymmetry of the distribution curves of the two conditions is similar.

WebThe degree of kurtosis of distribution is measured relative to the peakedness of normal curve. In other words, measures of kurtosis tell us the extent of which a distribution is more peaked or flat-topped than the normal curve.
