Step 1: Range of the data = higher value - lower value = 60 - 9 = 51
Step 2: Width = = = 10.2 ˜ 11
Step 3: Construct the class limits (daily sales of books) with width 11, so that the least and highest values have been included.
Step 4: The class limits, boundaries, tally marks and the frequency for each class (number of tally marks) are shown in the table.
Step 6: Since the frequency is more for the class interval 9 - 19, the sales are maximum in this limit.
