Connect measures of center and variation to the story in the data.

Adoption Records

Use the records below for Questions 1–4. IQR means interquartile range. MAD means mean absolute deviation.

A shelter records the days from arrival to adoption for 10 animals: 1, 2, 2, 3, 3, 4, 5, 6, 7, 27. All records are accurate. In the histogram, each interval includes its left endpoint but not its right endpoint.

Select the two observations that matter when choosing a summary of typical adoption times.

The distribution has a long tail toward longer times.The empty intervals make the mean impossible to calculate.One animal's time is far above the other nine times.The distribution is balanced on both sides of its center.
