how to find class widths??
posted by PALLAVI on .
can someone tell me how to calculate class width.
suppose the number of classes and class widh being 5 and 12 respectively.form a grouped frequency distribution..
the maximum is 98 while the minimum is 12.
Should i calculate it: maximum - minimum that is 98-12=76
to know how many classes i want, for ex: 5, should i divide 76 by 5?
