- arrange the data in ascending order
- the sum of data divided by how many numbers there are in the data
- with an outlier the mean is less accurate (average)
1 2 3 4 5
1+2+3+4+5=15
15 divided by 5 equals 3
3 is the mean
- arrange the data in ascending order
- the middle number in a set of data
- if there are 2 middle numbers you find the mean of them
- great to use when there is an outlier
1 2 3 4 5
1 5
2 4
3
3 is the median
- arrange the data in ascending order
- the most frequently used number in the data
- the data that appears the most
- you can have more than one mode
- you can have no mode
1 2 3 3 4
3 appears the most
3 is the mode
- arrange the data in ascending order
- subtract the smallest data from the largest data
- large range = outlier
1 2 3 4 5
5 is the largest number
1 is the smallest number
5-1=4
4 is the range
This is a video that I found on youtube that had to do with mean, median, and mode.
