Answer 2

If the first four central moments of distribution are 0, 2.5, 0.7 and 18.75, the following can be stated:-

• The third moment, in particular, deals with the skewness. It gives an idea about the degree of skewness present in the data. Thus, the skewness of the given data is 0.7
• The fourth moment helps to determine if the data is more peaked or more flat than normal. In other words, it measures kurtosis. And, for the given data, kurtosis is 18.75
