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

Impact Evaluation of the Minnesota Reading Corps K-3 Program. The limited number of previous evaluations on volunteer-only tutoring programs has shown variation in their effectiveness to improve children’s literacy proficiency. In 2014, NORC at the University of Chicago completed an evaluation of an AmeriCorps literacy intervention program, the Minnesota Reading Corps, which showed that volunteer AmeriCorps members can produce significantly greater increases in student literacy outcomes among Kindergarten, first and third grade students over one semester of tutoring. More

MCC Impact Evaluation Services in Benin. NORC is designing, coordinating, and implementing rigorous impact evaluations of the Access to Land and Access to Credit components of MCC's programs in Benin. The impact evaluations will measure the contribution of these interventions to changing household income in the project intervention areas as well as examine the total value of additional investment on targeted rural land parcels.

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

Togo Service Delivery Indicators (Health). The World Bank has contracted NORC to carry out data collection, produce a clean data set, deliver a country report, and create a data archive for the Service Delivery Indicator (SDI) survey of health clinics in Togo. The SDI is a set of 20 indicators designed to examine the availability of staff and resources in the health and education sectors in over a dozen African countries via in-depth surveys of clinic/school management as well as individual clinicians and teachers.  More
