Now,
– 1.5
= 17 – (1.5
22) = -16 and
+ 1.5
=
39 + (1.5
22) = 72. Since, 101 > 72, the value of 101 is an outlier relative to
the rest of the values in the data set (based on the
Inner Fence Test
). That
is, the number of medals won by the United States is an outlier relative to
the numbers won by the other 19 countries for the 1996 Atlanta Olympic
Games, based on the
Inner Fence Test
.
Using the
Basic Statistics
workbook, we can verify this conclusion. Refer
to
Figure 4-25
. The data were entered in the Data 1 column.
