Sinaya found the heart rates of the students in her
class and decided to make a dot plot to look at the
data. Below are the heart rates:
1. What is the heart rate for the student with the
lowest rate? The highest rate?
2. How many students had a heart rate greater than 86?
3. What fraction of the students had a heart rate less than
82?
4. What is the most common heart rate?
5. What is the general shape of the dot plot?
6. What heart rate describes the center of the data?
7. What heart rates are the most unusual heart rates?
8. If Sinaya’s teacher asked what the typical heart rate for
a 6th grader is, what would you say? Why?

1. What is a dot plot? How do
you make one?
2. How do dot plots help you
analyze data?
