Answers: 5, 6, 7
Work Shown:
Data set = {3, 6, 5, 5, 5, 7, 6, 4, 6, 7, 7, 3}
Sorted data set = {3, 3, 4, 5, 5, 5, 6, 6, 6, 7, 7, 7}
We see that the numbers 5, 6, and 7 show up exactly three times. This is the most frequent compared to something like 4 that only shows up once. Therefore, the modes are 5, 6, 7.
