Statistical Design and Analysis

​​NORC statisticians and methodologists have pioneered innovations in all aspects of survey research, from understanding cognitive processes underlying respondents’ reaction to surveys and survey instrumentation to rigorous, efficient methods for conducting surveys and advanced techniques for analysis and interpretation of survey data. NORC boasts several world-renowned statisticians and methodologists, including five Fellows of the American Statistical Association.

NORC’s work in the area of respondent cognitive processes culminated in a number of key publications in the field of cognitive research, and continues to be a major strength in our organization's repertoire. NORC’s Statistics and Methodology Department makes substantial contributions to virtually all NORC projects and builds the methodological infrastructure that underlies all major NORC studies. This includes establishing statistical standards for use throughout the organization to ensure consistently high quality in the areas of sampling design and execution, development and testing of questionnaires and other instruments, statistical process control, design and development of estimation systems, statistical computing, disclosure and confidentiality analysis, record linkage, unduplication, and geocoding. In addition to these support functions, NORC statisticians and methodologists develop and execute projects with particular statistical or methodological complexities and assist social scientists from all parts of the organization in conducting research-related data analysis.

Specific areas of expertise include:

Representative Projects

Evaluation of Primary Care/Mental Health Integration Project. NORC is working with Family Services Inc. to evaluate the effectiveness of a Behavioral  Health/Primary Care (BH/PC) integration project for adults with serious mental illness in Montgomery County Maryland. More

Integrated Research in Health and Aging: Early Results from the National Social Life Health and Aging Project (NSHAP) Wave 2. NORC's Center on the Demography and Economics of Aging was awarded a grant from National Institute of Health's (NIH) National Institute on Aging (NIA) to host a two day conference that will emphasize formal and informal discussion on innovative uses of the National Social Life Health and Aging Project (NSHAP) Wave 2 data. More

Kenya Urban Program Baseline Study. The World Bank has contracted with NORC at the University of Chicago to undertake a baseline study of the demographic, infrastructure, and economic profile of 15 Kenyan municipalities. More

National Immunization Survey. The NIS, administered by NORC since 2005, monitors childhood immunization coverage for the Centers for Disease Control and Prevention (CDC). This household survey screens more than 6 million sampled telephone lines yearly. The NIS Provider Survey requests permission to contact eligible children’s medical providers, and sends these providers an Immunization History Questionnaire. Household and provider data are combined to produce timely estimates of children’s vaccination coverage rate for national, state and local areas. A companion survey, the NIS-Teen, monitors vaccination coverage among teenagers aged 13-17 years. More

State-specific Design Parameters for Designing Better Evaluation Studies. This IES-funded project seeks to use State Longitudinal Data Systems (SLDS) to estimate variance components and intraclass correlations for use in multi-level study designs in education.  Having plausible values of intraclass correlations is essential to planning how many schools and students are needed for an evaluation design.  This project is a continuation of efforts by Hedges and Hedberg to provide guidance on these parameters to the research community. Whereas their previous work used national probability samples to estimate these parameters, the current project uses state data. More
