A distribution is said to be symmetric if the relative frequency (or probability) is the same the same distance either side of its centre, m. Mathematically, the distribution of X-m is then the same as the distribution of m-X.The mean and median of a symmetric distribution are equal.The most important symmetric distribution is the normal distribution, which is unimodal and therefore is symmetric about the mode.athematically, the distribution of X-m is then the same as the distribution of m-X.

when calculating a relative frequency distribution? â¢SPSS âPercentâ column includes all cases â¢SPSS âValid Percentâ excludes any âMissingâ [0 = IAP; 8 = DK; 9 = NA] For a variable with K categories, the valid N is the sum of the frequencies, f i, across all K categories (where the
