CBSE - IX - Mathematics - Statistics
I am supposed to make a frequency polygon where the classes are 0.5-6.5,6.5-12.5 and so on.the class size is 6 and the first class mark is 3.5.As per the rules i calculated the class mark of the class preceeding 0.5-6.5 which is -2.5. My question is how to plot -2.5 on the histogram, where there is a kink? Moreover, between 3.5 and -2.5 how do we find out the origin?
