About the National Data

Data

Data Source:  Youth Risk Behavior Surveillance System (YRBSS), CDC/NCCDPHP

Baseline: 23.6 percent of students in grades 9 through 12 reported that they had engaged in physical fighting in the past 12 months in 2017

Target: 20.9 percent

Numerator
Number of students in grades 9 through 12 who report being in a physical fight at least 1 time during the past 12 months.
Denominator
Number of students in grades 9 through 12.
Target-setting method
Minimal statistical significance
Target-setting method details
Minimal statistical significance, assuming the same standard error for the target as for the baseline.
Target-setting method justification
Trend data were evaluated for this objective, but it was not possible to project a target because the 2017 estimate moved away from the desired direction. The standard error was used to calculate a target based on minimal statistical significance, assuming the same standard error for the target as for the baseline. This method was used because it was a statistically significant improvement from the baseline.
