Which one of the following measures is determined only after the construction of cumulative frequency distribution?
A. Mean

B. Median

C. Mode

D. None of these

Answer :

Mean and mode does not require construction of cumulative frequency, but median necessarily requires construction of cumulative frequency, unless it is raw data (in which median is the (n/2)th value, when there are n number of observations; and the average of (n/2)th and (n/2 + 1)th values, when there are n observations).
