Question

what is used to calculate median​

Answer 1

Answer:

To calculate the median. Arrange your numbers in numerical order. Count how many numbers you have. If you have an odd number, divide by 2 and round up to get the position of the median number

Answer 2

Answer:

Step-by-step explanation:

To calculate median we follow the following steps:-

Rule1- Arrange either ascending or descending order.

Rule2- Check the total number of term are even or odd.

If Even - Median = $\frac{(\frac{n}{2})th ~term +(\frac{n}{2}+1)th~term }{2}$

If Odd - Median = $(\frac{n+1}{2})th~term$

Ex- Calculate the median of Raw data ,

      1,  4,  7,  8,   2,  3,  5 .

Solution-

   Rule1- Arrange either ascending or descending order.

            In ascending order = 1 ,  2,  3,  4 ,  5,  7,  8 .

  Rule2- Check the total number of term are even or odd.

           Total number of term = 7  ( odd )

  So,

        Median = $(\frac{n+1}{2})th ~term$

                     = $(\frac{7+1}{2})th~term$

                     = $(\frac{8}{2})th~term$

                     = $4 th ~term$

 And fourth term = 4.

Therefore median is 4.
