NCHS maintains an active program in statistical
research and methodology. The major components of that program are briefly described
Cognition and Survey Measurement
The National Laboratory for Collaborative Research in Cognition and Survey Measurement
applies cognitive methods in questionnaire design research, and was a pioneering effort
when established in 1985. In collaboration with other Center programs, the Laboratory
develops and tests NCHS data collection instruments. It also supports a questionnaire
design research program in collaboration with university scientists by means of research
Statistical Methods Research is undertaken at the Center on analytic methods applicable to NCHS'
registration systems and sample surveys. Current projects include the development of
computer software for the analysis of survey data, methods for model and design-based
State estimates, and random effect models for analyzing longitudinal data.
Statistical Technology The Center conducts a program of contract and intramural research on automated
statistical and graphical technology. Current applications include automated mapping,
statistical computing methods, geographic information systems, statistical graphics, and
The Survey Design program involves the design and evaluation of the sample plans for many
of NCHS' surveys to improve their efficiency and analytical capability. Current research
focuses on linked survey designs, designs for State telephone surveys, nonresponse
adjustments, and estimation of sampling errors for rare events. In addition, the Center
maintains an active program in monitoring data quality.
