See below

Step-by-step explanation:

The mean of a data set is what the average value is. For example, the mean of 3, 6, and 9 is (3+6+9)/3 = 18/3 = 6.

The median of a data set is the middlemost value from least to greatest. For example, in {3,6,9}, the median is 6 because it's the middlemost value.

The mode of a data set is the most frequent value. For example, in {1,1,2,2,2,3,5,6,6}, we can see that the mode is 2 because it appears the most frequently in the data set.
