Survey Research Aids
Creative Research Systems offers a series of free aids for survey researchers. The first is an online sample size calculator. It can tell you how many people to interview to get a desired accuracy level for your surveys. It can also tell you the plus or minus figure for a sample you already have.
Another article at this site explains statistical significance. This article first appeared in our newsletter DataFile and has since been reprinted in several magazines. Those new to survey research can find an introduction with many useful dos and don'ts on our survey design page.
Correlation is a statistical technique that can tell you if two variables are related. Researchers unfamiliar with this technique will find the correlation page useful. In addition to software and information, Creative Research Systems also offers web survey hosting services.
Companies that provide interviewing services using The Survey System are also listed on our site. The Survey System users can get ideas and save keyboarding by downloading sample question files that contain common questions and answers.
