Twenty-five students are asked to rate how important it is to reduce pollution on a scale of 0 to 10. A rating of 0 means “not at all important” and a rating of 10 means “very important.” Here is a dot plot of their responses.
Explain why a rating of 6 is not a good description of the center of this data set.
The dot plots show the time it takes to get to school for ten sixth-grade students from the United States, Canada, Australia, New Zealand, and South Africa.
