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). The following conventions are used here to interpret the RSE.[[br]][[br]] * A dash (-) means that the relative standard error (RSE) is below 0.30 and the count or rate may be considered stable. [[br]] Problems with statistical instability typically occur when there is a small number of health events in a small population. For more information on statistical stability, visit the MT-IBIS Reliability & Validity page []. [[br]][[br]]

Weighted Survey Data

The percentages reported above have been produced by weighting the sample so that the results better represent the Montana population. The sample sizes reported in the table are unweighted. Percentages calculated using the unweighted sample sizes will not be accurate.

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%.

U.S. Data

Survey Sample

The survey is conducted using scientific telephone survey methods. Excluded are adults living in households without a telephone and those living in group quarters such as nursing homes, military barracks, and prisons. Results have been weighted to the adult population by age, sex, race/ethnicity, region, telephone ownership, education level, marital status, and home ownership.


The denominator includes all survey respondents ages 18 years and older 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.
