About the National Data
Data
Baseline: 25.4 percent of students in grades 9 through 12 got sufficient sleep on an average school night in 2017
Target: 27.4 percent
Numerator
Number of students in grades 9 through 12 who sleep for 8 or more hours per night.
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 trend was moving 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.
