Answer 1

Answer:

Median = 6

Step-by-step explanation:

We are provided with the following data given below in ascending order;

      x                      f                          cf

      2                     13                        13

      3                      7                        20

      5                      8                        28

      6                      9                        37

      7                      12                       49

      9                     14                        63

      10                    11                         74

                      ∑f = 74    

Now, First we calculate $\frac{N}{2}$  ,where N = ∑f ,i.e. $\frac{74}{2}$ = 37

Here, the cumulative frequency(cf) just greater than or equal to 37 is 37.  

Therefore, value of x corresponding to 37 is 6.

Hence median of given data is 6.
