Chart Not AvailableThe data are grouped by more dimensions than the chart is capable of displaying. If you would like this chart you will need to remove one or more grouping selections on the query definition builder page and then resubmit the query request or choose a different chart that supports multiple dimensions.
Map Not AvailableThe data are grouped by 2 or more dimensions. Maps can only be displayed when the data are grouped by a single geographical dimension. If you would like a map, you will need to return to the query definition page and set the Display By (category) to the "Geography" selection and clear the Group By (series) selection. Then resubmit the query.
Question Wording:Based on a series of questions. Sigmoidoscopy and colonoscopy are exams in which a tube is inserted in the rectum to view the bowel for signs of cancer or other health problems. Have you ever had either of these exams? How long has it been since you had your last sigmoidoscopy or colonoscopy? Query includes only those persons age 50-75.
Statistical StabilityStatistical 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.
Weighted Survey DataThe percentages reported above have been produced by weighting the sample so that the results better represent the Hawaii population.
Survey SampleThe survey is conducted using scientific telephone survey methods. Both cell phones and land lines are included. Excluded are adults living in group quarters with a central phone system such as college dormitories, nursing homes, military barracks, and prisons. Results have been weighted to the adult population by age, gender, race, education, marital status, home ownership, telephone source (landline versus cell phone), and county of residence.
Average Annual Population EstimateThe 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.
Asymmetric Confidence IntervalsThe confidence bounds are asymmetric. They do not extend evenly above and below the percentage, especially as the percentage gets close to 0% or 100%.
