[ashiqbal]

u will end it at 4

OHk! confirmed?

 

[MustafaMotani]

OHk! confirmed?

its frequency polygon, not CF , wat I told u was for CF polygon..
here I dont think that u end somewhere its just joining mid points

Cumulative frequency polygon? now u r creeping me out!

 

[MustafaMotani]

Wat I told u was for cumulative frequency polygon (havent u heard of it??) that we wolud start the CF curve from 4.

In frequency polygon u just join mid points

here i try to explain u in simple words !! on x - axis labell the time for 1 unit 1 min uptil 12...!! find the mid-point of intervals like for 4 < t< 6 it is 5 !! plot ( 5 , 21) as given in the table !! plot the other points the same way !! after plotting start joining them , begin from 4 and end at 12 !!

hope u understand it !!

do correct me if I am wrong !
