WebFor example: Let the raw data be 2, 10, 18, 25, 15, 16, 15, 3, 27, 17, 15, 16. The cumulative frequency of 15 = 6 (Since, values ≤ 15 are 2, 10, 15, 15, 3, 15). The cumulative frequency of a class interval (overlapping or nonoverlapping) is the sum of the frequencies of earlier class intervals and the concerned class interval. WebThe results were as follows: Set up a frequency table for this set of data values. Step 1: Construct a table with three columns, and then write the data groups or class intervals in the first column. The size of each group is 40.
