Geographies: U.S. States
Data Type: String
Purpose:
A confidence interval is a range of values within which the “true” percent lies. The YRBS is a random sample of students rather than a survey of all students, so confidence intervals are constructed. A 95% confidence interval means that if a survey were repeated many times (in all probability each survey would have different schools randomly selected) the “true” percent would fall within the interval 95% of the time.
Limitations:
These data represent results from a survey. Be wary of interpreting data when there are large confidence intervals around the estimates.
