Mean
Median
- Arrange in ascending order
- Add all the data together, then divide the sum by the number of data
- If there is an outlier in the data, it is not as accurate
Median- Arrange in ascending order
- Find the middle number
- If there are two middle numbers, add them up and divide them in half
- It is better to use the median than the mean when there is an outlier, because the median will cross it out
Mode- Arrange in ascending order
- Find the number that occurs most
- There can be more than one mode
- There can also be no mode
Range- Arrange in numerical order
- Subtract the smallest data from the largest data
- If the range is big, it can tell you that there probably is an outlier
Here is a video I found about MMM
