454. Find the median for following distribution:

Here,

straight N space equals space 50 space space rightwards double arrow space straight N over 2 equals 25

c.f. just greater than

straight N over 2 left parenthesis or space 25 right parenthesis

is 30
∴ Median class is 30 - 40

rightwards double arrow

l = 30, h = 10, f = 10, C = 20
Median =

l italic plus h over f open parentheses straight N over 2 minus straight C close parentheses space equals space 30 plus 10 over 10 left parenthesis 25 minus 20 right parenthesis space equals space 30 plus 5 space equals space 35
