Question

A survey taken of 140 sports fans asked the question: "What is the most you have ever spent for a ticket to a sporting event?" The five-number summary for the data collected is: min - 85, Q1-130, Median- 145, Q3- 150, Max -250 Should the smallest observation be classified as an outlier? a.Yes b.No

Answer 1

The IQR is 150 - 130 = 20. Using the 1.5(IQR) criterion we get 130 -1.5(20) = 100. Since the smallest observation of 85 is smaller than 100, it should be considered an outlier
