No other number appears that many times. Therefore the mode of their ages is 6. Example 2: Find the mode of the data set 1, 2, 2, 3, 3, 4, 5. The most common number to appear on the list are 2 and 3. Therefore the mode of data are 2 and 3. This data set is bimodal. Example 3: Find the mode of the data: 12, 15 19 20, 12, 14, 15, 12, 11 The most common number to appear on the list is 12 and it occurs three times. Therefore the mode of the data is 12.
