Attempt of the following sub questions:
The following table shows ages of 300 patients getting medical treatment in a hospital on a particular day:

Find the median age of patient.


= = 150


150 lies in the range of 102 to 157


Therefore cf = 102 , f = 55 and median class = 30 – 40


L = lower limit of median class = 30


h = difference in lower limit and upper limit of median class = 10


Formula:


Median = L + ( – cf) ×


⇒ Median = 30 + (150 – 102) ×


⇒ Median = 30 + 48 ×


⇒ Median = 30 +


⇒ Median = 30 + 4.36 × 2


⇒ Median = 30 + 8.72


⇒ Median = 38.72


Therefore median age of patient is 38.72 years
