Question

# Compute the median from the following table

- 36.55
- 35.55
- 40.05
- None of these

## The correct answer is: 36.55

. Here n = 159, which is odd

Median number,

which is in the class 30-40. (see the row of cumulative frequency 95, which contains 80).

Hence median class is 30-40.

\ We have,

l = Lower limit of median class = 30

f = Frequency of median class = 45

C = Total of all frequencies preceding median class

= 50

i = Width of class interval of median class = 10

\ Required median

.
