Greater than cumulative frequency formula
WebThe formula is as follows: Mean = A + (∑fd’/∑f)×C C = The common factor using which deviations are converted to step-deviations Note: In this method step-deviation denoted by d’ is used and not d. d’= (X-A)/C Here, X = The value of the item, A = Assumed value of mean and C = Common factor chosen WebThe cumulative frequency for the first interval is 5. The cumulative frequency for the second interval is 5 + 31 = 36, and so on. Again, the final cumulative frequency value is 200, which matches the frequency in …
