Mean- Add up all values and divide it by how many values there are.

Median- The middle number in a set of ordered values, might be the mean of 2 middle values.

Mode- The value that shows up the most.

Range- Positive difference between largest and smallest values.

Outlier- Values that are too big or too small compared to the other values.

Eg.  18, 19, 79, 17, 20, 12

Mean = 12, 17, 18, 19, 20, 79
             12+17+18+19+20+79 =27.5
                             6

Median = 12, 17, 18, 19, 20, 79 =18.5


Mode = 12, 17, 18, 19, 20, 79 = No Mode


Range = 12, 17, 18, 19, 20, 79
              79+12=91


Outlier = 12, 17, 18, 19, 20, 79 = 79
                
Red = ordered from least to greatest
Blue = Answer
