Question

Calculate the median of the following data marks no of students 0-10 5 10-30 15 30-60 30 60-80 8 80-90 2​

Answer 1

Answer:

Step-by-step explanation:

Here, total frequency(N)=5+15+30+8+2=60

∴N2=602=30

Cumulative frequency equal to or just greater than 30 is 50 that means our Median class is 30−60.

∴ Lower boundary class(l) = 30

Previous cumulative frequency(F) = 20

Median Class Frequency(f) = 30

Interval(i) = 30

Median = l+((N2)−Ff)∗i

= 30+(30−2030)∗30

= 30+10=40

Median=40
