Question

1.
The upper limit of median class is
(A) 15
(B) 10
(C) 20
(D) 25​

Answer 1

Option A. 15

Step-by-step explanation:

Frequency distribution data :

Class                       frequency                  cf  

0-5                               8                            8

5-10                             10                          18

10-15                            19                          37

15-20                          25                          62

20-25                           8                         70

                           n =  70    

To find median class :

= Value of $(\frac{n}{2} )th$ observation

= value of $(\frac{70}{2})th$ observation                      

= value of 35th observation

From the column of cumulative frequency cf, we find that the 35th observation lies in the class 10-15.

So the median class is 10-15.

and the Upper limit of median class is 15.

Option A. 15 is the answer.
