\(\sum f_i\) = 250
Finding Median
Median = I + \(\cfrac{{\frac{n}2-cf}}f\) x h
Here,
\(\cfrac N2\) = \(\cfrac{250}2\) = 125
∴ 2 - 3 is median class
And,
t = 2
h = 1 - 0 = 1
cf = 120
Putting values in formula
Medium = I + \(\cfrac{{\frac{n}2-cf}}f\) x h
= 2 + \(\cfrac{125-120}{62}\) x 1
= 2 + \(\cfrac5{62}\)
= 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%
