11.1 Outliers
Day 2
5/6
Outlier: a value that is much greater or much less than most of the other values in the data set.
Ex. 4: You are competing in an air hockey tournament. The winning scores for the first 10 games are:
14, 15, 15, 17, 11, 15, 13, 12, 15, 13
a. Find for the data set:
mean:
median:
mode:
range:
SD:
b. The winning score in the next game is an outlier, 3. Find the new mean, median, mode, range, and standard deviation.
mean:
median:
mode:
range:
SD:

The data set below gives a city's high temperatures (in degrees F) during a 15­day period.
36, 37, 36, 34, 49, 33, 30, 30, 32, 31, 31, 32, 32, 33, 35
15. Identify the outlier in the data set.
16. Find the mean, median, mode, range, and standard deviation of the data set when the outlier IS included and when it IS NOT.
