Ex 13.3, 7 The distribution below gives the weights of 30 students of a class. Find the median weight of the students. Finding Median Median = l + (𝑁/2 βˆ’π‘π‘“)/𝑓 Γ— h Here, 𝑡/𝟐 ∴ 55 – 60 is median class And, l = h = cf = f = Putting values in formula Median = l + (𝑁/2 βˆ’π‘π‘“)/𝑓 Γ— h = 55 + (15 βˆ’13)/6 Γ— 5 = 55 + 2/6 Γ— 5 = 55 + 1.67 = 56.67 Therefore, Median weight is 56.67kg
