Survey Methodology, Design, and Analysis
Sample surveys are a vital tool in cancer surveillance and control. The Statistical Research and Applications Branch (SRAB) has provided statistical collaboration and support for the design and analysis of sample surveys, and has participated in the development of new methods.
Examples of completed and ongoing projects include:
- model-based small area estimates for cancer-related measures, including several cancer risk factors and screening behaviors, tobacco use and policies, and cancer-related knowledge. See Small Area Estimates for Cancer-Related Measures for more information;
- statistical design support (sample size determination, power analysis, weighting) for select NCI-supported surveys, such as the Health Information National Trends Survey (HINTS), the Tobacco Use Supplement to the Current Population Survey (CPS-TUS), and the Family Life, Activity, Sun, Health, and Eating (FLASHE) study;
- statistical analysis assistance (statistical modeling and analysis of trends) to researchers for select studies utilizing data obtained from a complex survey design;
- support of software enhancements for analysis of complex survey data.
