Question

claculate the mode..​

Answer 1

Answer:

Mode = 28

Step-by-step explanation:

We are given with the following data;

       Class Interval                  f

             0 - 10                          20

            10 - 20                         24

            20 - 30                         40

            30 - 40                         36

            40 - 50                         20

Firstly from the above data we observe that the highest frequency is 40 and the class interval corresponding to this is 20 - 30;                                                         So the modal class is 20 - 30.

Now, formula for calculating mode is given by;

             Mode = $x_L + \frac{f_m - f_m_-_1}{(f_m - f_m_-_1)+(f_m -f_m_+_1)} *i$

 where,    $x_L$   = Lower limit of modal class.

                $f_m$   = Frequency of modal class.

               $f_m_-_1$  = Frequency just before the frequency of modal class.

               $f_m_+_1$   = Frequency just after the frequency of modal class.

                     i  =  width of class interval

        Mode = $20 + \frac{40 - 24}{(40 - 24)+(40 -36)} *10$ = 28 .

Hence, mode of the following frequency distribution is 28 .
