The survey was advertised by memoranda, posters, word of mouth, and content in various media outlets. Employees were able to call and request a copy of the survey if they did not receive one in the original mailing, or if they required a replacement copy. Surveys were eventually mailed to 143,377 individuals. Almost one-third of the state employees responded, resulting in a response pool of 45,598 employees. But the large number of respondents, the general similarity of the respondents demographics with demographics known for classified employees, and the patterns of response all lend credence to the results.
Most surveys report a sampling error or confidence interval.
Because this survey is not based on a probability sample, it would be inappropriate to report one here. The extent to which these results would vary from results obtained if all state employees had responded is unknown. But it seems unlikely that response distributions for items with heavily skewed patterns of response would be significantly altered by the inclusion of the other two-thirds of state employees.
