The document defines and provides examples for calculating the mean, median, and mode of data sets. It explains that the mode is the most common number, the median is the middle number once the data is ordered, and the mean is the average found by adding all numbers and dividing by the count. It then provides 6 practice data sets and asks the reader to calculate the mean, median, and mode of each, showing their work.

1. Mean, Median and Mode Explanation and Practice Questions

2. Mode Mode = the most common number, or the number that you see the most times. 5, 6, 7, 5, 5, 6, 5, 7 What is the Mode of this set of numbers? The answer is 5 because there are four 5s in the list.

3. Median

4. Mean Mean = average Use these numbers: 2, 5, 4, 6, 4, 3, 7 Step 1 – Add up all the numbers in the set. 2 + 5 + 3 + 4 + 4 + 3 + 7 = 28 Step 2 – Divide by the amount of numbers in the set. 2 + 5 + 3 + 4 + 4 + 3 + 7 28  7 = 4 7 numbers Step 3 – So, 4 is your Mean.

5. Set A Find the Mean, Median and Mode of this set of numbers. Make sure you show your work when necessary. (the mean could be a decimal number). 2, 5, 6, 4, 5, 6, 1, 3, 4, 2, 5, 6, 3, 5

6. Set B Find the Mean, Median and Mode of this set of numbers. Make sure you show your work when necessary. (the mean could be a decimal number). 7, 8, 9, 10, 10, 4, 6, 8, 9, 10, 7, 10

7. Set C Find the Mean, Median and Mode of this set of numbers. Make sure you show your work when necessary. (the mean could be a decimal number). 15, 15, 13, 15, 15, 13, 10, 12, 14, 15, 12

8. Set D Find the Mean, Median and Mode of this set of numbers. Make sure you show your work when necessary. (the mean could be a decimal number). 2, 5, 3, 1, 3, 2, 5, 3, 2, 1, 3, 3, 3, 4, 5, 3, 2, 3, 5, 1, 3, 3, 4, 2, 3, 2, 3

9. Set E Find the Mean, Median and Mode of this set of numbers. Make sure you show your work when necessary. (the mean could be a decimal number). 19, 20, 18, 18, 15, 20, 15, 19, 17, 17, 18, 19, 17, 15, 17, 17, 19 Please try this one without a calculator first.

10. Set F Find the Mean, Median and Mode of this set of numbers. Make sure you show your work when necessary. (the mean could be a decimal number). 95, 100, 90, 88, 87, 79, 90, 67, 45, 80, 76, 88 Please try this one without a calculator first.
