The boxplots below give the cardiovascular disease (CVD) rate as a percentage of total deaths for 160 countries. Which of the following statements is a valid conclusion that can be drawn from the boxplots? Check all that apply.
- The medians are close. This suggests that the typical CVD mortality rate is about the same for both groups of countries.
- If we use Q1 and Q3 to define a typical range of values, the countries with a high per-capita supply of vegetable protein have a typical range of CVD mortality rates between 31 and 47.5.
- If we use range as a measure of variability, then the group of countries with a low per-capita supply of vegetable protein has more variability.
- If we use the interquartile range as a measure of variability, then the group of countries with a low per-capita supply of vegetable protein has less variability.
