- 1. 95% Confidence Interval
- A confidence interval is a range of values within which the true rate is expected to fall. If the confidence intervals of two groups (such as individual Vermont counties and Vermont as a whole) overlap, then any difference between the two rates is not statistically significant. All confidence intervals in this report are calculated at the 95 percent confidence level.
- 2. Prevalence
- The number of total cases who have an attribute or disease divided by the number in the population at risk. Prevalence may be age-adjusted.
- 3. Risk Factor
- An aspect of personal behavior or life-style, an environmental exposure or an inborn or inherited characteristic, which on the basis of epidemiologic evidence is known to be associated with health-related conditions(s) considered important to prevent.
- 4. Comparisons & Statistical Significance
- When comparing two groups (such as individual Vermont counties and Vermont as a whole), overlap of the two rates show that the two rates are not statistically significant
- 5. Age-Adjustment
- Age-adjusting is a statistical method used when comparing rates from populations that differ geographically (e.g. counties) or over time. This allows the comparison of rates among populations having different age distributions by standardizing the age-specific rates in each population to one standard population.
