First, organize the data in ascending order: 3, 3, 4, 4, 5, 5, 5, 5, 6, 6, 6, 7, 7, 7, 7, 9. Mean = (3+3+4+4+5+5+5+5+6+6+6+7+7+7+7+9) / 16 = 89 / 16 = 5.5625. Median = (5+6)/2 = 5.5 (since there are an even number of data points, the median is the average of the two middle numbers). Mode = 5 (the number that appears most frequently).
