Interpreting Clusters and Outliers

Question 4 • 25-26 8th Grade Mathematics - Americus

The table below shows a set of data.Data xy6717687.5697.5658638.25628.25649609.561Which of the following points, if added to the table, would be an outlier?

Answer
A
(7, 73)
B
(7.5, 70)
C
(8, 35)
D
(8.5, 66)

Explanation

The table’s points follow a general pattern in which y stays around the 60s and low 70s as x ranges from about 6 to 9. At x = 8, the value y = 35 is far below that pattern, while the other choices are in the range of the existing y-values. Therefore, (8, 35) would be an outlier.
