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

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).
