Data Notes

Question Wording:

During the past 30 days, on how many days did you text or e-mail while driving a car or other vehicle?

Statistical Stability

Statistical stability, reported in the data table, is based on a statistic called the "Relative Standard Error," or RSE, which is the standard error expressed as a proportion of the point estimate (e.g., 30% of the point estimate).

"Stable" is displayed when the relative standard error (RSE) is below 0.30 and the count or rate may be considered stable.

"Unstable" is displayed when the RSE is 0.30-0.50. An unstable count or rate may fluctuate widely across time periods due to random variation (chance).

"Very Unstable" is displayed when the RSE is greater than 0.50. A very unstable count or rate should not be used to inform decision. Problems with statistical instability typically occur when there is a small number of health events in a small population. You may combine years or otherwise increase the population size used in the query to achieve a more stable count or rate.

"No Variance" is displayed when there is no record, or only one record in the sample population, for the selected indicator and demographics.

Suppression of Estimates

According to CDC guidelines, a minimum of 100 students must answer a question in order for it to be reported. Where the number of students is below 100, not reportable, will appear in the table

Weighted Survey Data

The percentages reported above have been produced by weighting the sample so that the results better represent the population of Hawaii.

Data Issues

Survey Sample

YRBS uses a two-stage, stratified random sampling method to identify the sample. The sampling frame includes all students currently enrolled in grades 6-12 in a public school in the state of Hawaii. Two samples are taken: one for middle school (grades 6-8) and one for high school (grades 9-12). Results are weighted by sex, grade, and race/ethnicity to ensure accurate representation of the population.

Average Annual Population Estimate

The denominator includes all survey respondents except those with missing, don't know, and refused answers. If the query was limited to a particular sub-population-group, only those respondents are included in the denominator.

Asymmetric Confidence Intervals

The confidence bounds are asymmetric. They do not extend evenly above and below the percentage, especially as the percentage gets close to 0% or 100%.
