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.

The relative frequencies in the body of the table are called conditional frequencies or the conditional distribution. The table above shows relative frequencies for the whole table. Two-way tables can also show relative frequencies separately for the for rows and for columns. The table below shows relative frequencies for rows. Relative Frequency of Row. And the next table shows relative frequencies for columns.
