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
