                                        4.   in any __________ the value that appears the most is called as the mode.
                                        5.   Mode is that point in the distribution where there is highest ___________ .
                                        6.   in our daily life we often hear that the average height of an indian is ___________ .

                                      Characteristics of Mode

                                      there are following characteristics of mode based on the above description-
                                        1.   Mode is based on all the elements of the series therefore, there is no effect of very small as
                                             well as very big value element on it.
                                        2.   Mode depends on frequency. therefore, instead of value of elements, it is based on the value
                                             of frequency of that element that has the highest frequency. therefore, it is the smallest way
                                             to find out the mode,
                                        3.   Mode is not the highest value element but it can be the value of the element.
                                        4.   There is difficulty in finding out the mode in condition where there are two or more than two
                                             elements with the same highest frequency, in such a situation we have to describe more than
                                             two modes. for example- 1, 3, 4, 4, 6, 7, 6, 10, 7, 4, 7 we have 4 and 7 as the mode.

                                      Computation of Mode

                                      Normally it is said that computation of mode is very easy because it is value of the element that has
                                      the highest frequency. Therefore, by arranging any series in a systematic order we can find out which
                                      element has the highest frequency. With the help of given examples we will focus on the methods of
                                      calculating mode.

                                      Mode of Simple Series

                                      Calculation of mode in a simple series is very easy because in this the elements are arranged in the
                                      definite order according to their values and the element that has the highest frequency is the mode.
                                      this can be made clear with the help of the following example-


                                            Example 12   find the mode of given series
                                                         33,20, 35, 50, 37, 33, 35, 25, 35, 34 and 35

                                      solution: By arranging the elements according to their values, the situation will be like this-
                                      20, 25, 33, 33, 34, 35, 35, 35, 35, 37, 50.
                                      from the above order it is clear that 35 appears the most therefore it has the highest frequency.
                                      therefore, the mode of given series is 35.
                                                                          Mo = 35






                                          Notes    the symbol for mode is sometimes used as Z instead of Mo.
