Mean = 3 + 5 + 9 + 10 + 11 + 5 + 8 + 12 + 15 + 9 + 5 + 11 / 12 = 103 / 12 = 8.58
Median = 9
Mode = 5

- Add up all data values to get the sum
- Count the number of values in your data set
- Divide the sum by the count
- The mean is the same as the average value in a data set.
How to Find the Median
The median x˜ is the data value separating the upper half of a data set from the lower half.
- Arrange data values from lowest to highest value
- The median is the data value in the middle of the set
- If there are 2 data values in the middle the median is the mean of those 2 values.
