Interpretation of YRBS Trend Data
Compare State/District and National Results
The following links provide tables that compare 2011 state and district YRBS data with 2011 national YRBS data. Each table includes
- Selected state or district prevalence estimates and confidence intervals
- National prevalence estimates and confidence intervals
- Comparisons between the selected state or district and national data based on t-test analyses
The tables can be modified by clicking on the “Modify Table Data” link at the top of the table.
* States and districts listed above had weighted data for the 2011 YRBS. This means that the site achieved at least a 60% overall response rate. With weighted data, it is possible to say, for example, "X% of high school students in our state smoked cigarettes during the past month."
