yes Thanks alot Sir ;D
silvercameron:
thankyou sir, i got how to do it.
But could you pls answer my other question?
astarmathsandphysics:
Is that the quantiles question?

silvercameron:
no sir. I am sorry but this isnt exactly my doubt. I wanted to know how we find the quartiles for large data with no classes.
For example:
Score : 0 1 2 3 4 5 6
frequency : 36 94 48 15 7 3 1
astarmathsandphysics:
For this one, there are 36+94+48+15+7+3+1=214
I would do this:214/4=53.5 so the lower quartile is 1
For the upper quartile find 3/4*215=160.5 so the upper quartile is 2
More complicated methods exist but for S1 do as above..
