Question

In this lesson you learned how to identify an outlier in a data set. Use the following to determine the boundaries of the outliers. Quartile 1: 12 Quartile 3: 25 IQR: 14 (2 points) Any value that is below and any value above would be considered an outlier.

Answer 1

To determine the boundaries of the outliers, we can use the formula:

Lower Bound = Q1 - 1.5 * IQR
Upper Bound = Q3 + 1.5 * IQR

Substitute the given values:

Lower Bound = 12 - 1.5 * 14
Lower Bound = 12 - 21
Lower Bound = -9

Upper Bound = 25 + 1.5 * 14
Upper Bound = 25 + 21
Upper Bound = 46

Therefore, any value that is below -9 or above 46 would be considered an outlier in this data set.
