Module 2 Review

Based on a 2006 National Health Survey: We estimate 15.7% of boys and 11.2% of girls under 18 had at some point been diagnosed with asthma. What is the relative risk of boys developing asthma?

• 1.60
• 1.40
• 1.20
• 1.80

What is the percent increase or decrease in risk?

• Boys under 10 have a risk of asthma that is 40% higher than the risk of asthma for girls.

• Boys under 10 have a risk of asthma that is 40% lower than the risk of asthma for girls.

• Boys under 10 have a risk of asthma that is 30% higher than the risk of asthma for girls.

• Boys under 10 have a risk of asthma that is 30% lower than the risk of asthma for girls.

What is the relative frequency (to the nearest percent) of boys among those who cannot bike to school? 

• 4%
• 14%
• 13%
• 29%

To calculate the relative frequency, what ratio do you set up?
