Range and Outliers

Range - the positive difference between the largest and smallest values in a data set.
Outlier - a value that is smaller or larger than the other data value.
- a data set may have one or more outliers or no outliers.

Find the range:
a) 7, 4, 3, 6, 2, 5, 8, 3 ----> 2, 3, 3, 4, 5, 6, 7, 8 ----> 8-2 = 6
b) 11, 8, 8,5, 7, 6, 7, 6, 6---->5, 6, 6, 6, 7, 7, 8, 8,11--->11-5=6
c) -4, 3, -1, 0, 2 ----> -4, -1, 0, 2, 3 ----> 3-(-4) = 7
Find the outliers:
a) 18, 19, 79, 17, 20, 12 ---> 12, 17, 18, 19, 20, 79 ---> 79
b) 14, 14, 16, 15, 1, 16 ---> 1, 14, 14, 15, 16, 16 ---> 1
c) 98, 202, 99, 91, 2, 95, 89, 88 ---> 2, 88, 89, 91, 95, 98, 99, 202 ---> 2 and 202
