Hey,,,
Well Iam facing a simple problem that is causing me a big confusion and I cant find its explanation anywhere....
Usually in mathematics we see a question is the examination paper in statistics asking for the (MODAL CLASS)..................
and iam really not sure either to use the frequency or the frequency density to find it as in question 8 (A) In Oct/Nov 2009
paper 4 http://www.xtremepapers.net/CIE/Cambridge IGCSE/0580 - Mathematics/0580_w09_qp_4.pdf

So i would be really thankful if you help me :| :x :shock:

The modal class is the one with the highest frequency. So, look at the frequencies.5.5 <x<= 6.0.

 

[princesszahra]

modal class = class with the highest frequency
and in raw data modal value is the most repeated value

Thanks Guys.....here in the UAE they say that you should fing the frequency density to find the modal class....

 

[princesszahra]

u dont need frquecy density to get the modal class!!!!!!!!!
