Learning Goal: I’m working on a statistics question and need an explanation and answer to help me learn.
Use this activity to assess whether you and your peers can:
Students researching backpack weights gathered data from 45 elementary school children in the 3rd and 5th grades. The variable is “percent of body weight carried in the school backpack.” So a child who weighs 60 pounds and carries 9 pounds has a variable value of 15% (9 ÷ 60 = 0.15 = 15%). The American Chiropractic Association (ACA) recommends that children carry no more than 10% of their body weight.
When we analyze backpack weight as a percentage of body weight, how do 3rd and 5th graders compare? Are children in this study following the ACA recommendation?
|% of body weight carried in backpack||Third
Note: Left-hand end-points are included in each bin. So the 2nd bin contains students carrying 5% of their body weight.
