1. B. The values of data set A are less spread out compared to the values of data set B, since the interquartile range is smaller in data set A than in data set B.
2. A. The number of sales made each day in September is slightly greater on average compared to the number of sales made each day in October. The spread of the data is similar between the two months using the interquartile range. However, there is an outlier for the month of September, since the minimum value is quite a bit lower than the first quartile.
3. A. The number of vehicles traveling on the eastbound lane per hour during peak times is much greater compared to the westbound lane. The number of vehicles traveling on the westbound lane per hour during peak times has a significantly greater spread compared to the eastbound lane, since the interquartile range for the westbound lane is much larger than for the eastbound lane.
4. A. The distribution for 2019 is skewed right, and the distribution for 2020 is skewed left. One case worker had an unusually high number of cases in 2019, while one case worker had an unusually low number of cases in 2020.
5. D. The number of home runs hit by each team in 2019 is slightly greater on average compared to the number of home runs hit by each team in 2018. However, the spread for the number of home runs hit by each team in 2019 is about the same compared to 2018 when using the standard deviation.
