In probability theory and statistics, the cumulants κn of a probability distribution are a set of quantities that provide an alternative to the moments of the distribution. Any two probability distributions whose moments are identical will have identical cumulants as well, and vice versa. The first cumulant is the mean, the second cumulant is the variance, and the third cumulant is the same as the third central moment. But fourth and higher-order cumulants are not equal to central moments. In some cases theoretical treatments of problems in terms of cumulants are simpler than those using moments. In particular, when two or more random variables are statistically independent, the n-th-order cumulant of their sum is equal to the sum of their n-th-order cumulants. As well, the third and higher-order cumulants of a normal distribution are zero, and it is the only distribution with this property. Just as for moments, where joint moments are used for collections of random variables, it is possible to define joint cumulants. (Wikipedia).

CUMULATIVE Frequency Distributions (3-7)
Cumulative Distributions add the new scores to the previous scores, giving the accumulated scores. Cumulative Frequency (cf) is the number of scores at and below a particular score. The last entry will equal the number of cases (N). Cumulative Relative Frequency is the proportion of scores
