Range and Outliers

Range - Positive Difference between the largest and smallest values in a data set.

eg. 6,2,9,4,3 Re-order the data set.
2,3,4,6,9 Subtract smaller value from larger value.
9 - 2 = 7. 7 is your range.
eg. -8,-1,-3,-5 Re-order the data set.
-8,-5,-3,-1 Subtract smaller value from larger value.
(-8) - (-1) = 7

Outlier - A value that is much smaller or larger than the other data values, or the "outcast".
-A data set may have one or more outliers or no outliers at all.

Try to find the Range of the following.

a). 7,4,3,6,2,5,8,3 b).11,8,8,5,7,6,7,6,6 c). -4,3,-1,0,2

Try to find the Outlier of the following.

a). 18,19,79,17,20,12 b). 14,14,16,15,1,16 c). 98,202,99,91,2,95,89,88,94
