The Docking Institute of Public Affairs at Fort Hays State University surveyed a random sample of adult residents of Kansas age 18 and older to assess attitudes and opinions regarding various issues of interest to Kansas citizens. The survey sample consists of random Kansas landline telephone numbers and cellphone numbers. From March 23 to April 1st, a total of 1,308 Kansas residents were contacted through either landline telephone or cellphone, and 519 of them completed the survey, resulting in a 40% response rate (519/1,308). At a 95% confidence level, the margin of error for the full sample of 519 is 4.4%. A margin of error of 4.4% means that there is a 95% probability that findings among the sample vary no more than +/- 4.4% from the value that would be found if the entire population of interest (adult Kansas residents) were surveyed, assuming no response bias. The percentage of males and females in the sample were similar to the Kansas population.
