Question

I don't want the whole answer. I just want someone to calculate 20th percentile for me and explain me. Can someone please explain it ?​

Answer 1

draw the cumulative frequency polygon Vs the class limits graph

take cumulative frequency on y axis and limits on x-axis

now maximum value which is 10 we considered as 100% percentile so from that find 20th percentile

means 100%=10

then 20%=?

after finding that value draw the line from cumulative frequency which is y axis so where ever it is interesting the graph from that place draw perpendicular line to x-axis

where ever it intersects that value on x axis is your 20th percentile

if you didn't understand let me know I will send you the answer as well
