Answer 2

Given,

• n = 230
• l = 40
• cf = 76
• h = 10
• f = 65

To find,

• Median of the data

Solution,

We can simply find the median of the data by using the given conditions by the following formula:

     Median = L1 + h/f (N/2 -cf)

where L1 is the lower limit of the median class, h is the height of the class interval, cf is the cumulative frequency, f is the frequency.

                  = 40 + 10/ 65 (230/2 - 76)

                  = 40 + 10/65 (115-76)

                 = 40 + 10/65 (39)

                 = 40 + 6

                 = 46

Hence, if n =230, l =40,cf=76,h=10,f =65 then median is 46.
