Following is the distribution of the long jump competition in which 250 students participated. Find the median distance jumped by the students. Interpret the median Finding Median Median = l + (𝑁/2 −𝑐𝑓)/𝑓 × h Here, 𝑵/𝟐 ∴ 2 − 3 is median class And, l = h = cf = f = Putting values in formula Median = l + (𝑁/2 −𝑐𝑓)/𝑓 × h = 2 + (𝟏𝟐𝟓 −𝟏𝟐𝟎)/𝟔𝟐 × 1 = 2 + 5/62 = 2 + 0.0806 = 2.0806 Therefore, Median distance jumped by student is 2.0806 m By interpreting the median, We observe that 50% of students jump below 2.0806 m and 50% above it
