The IDC NRBA App is an interactive, browser-based application that can be used to analyze survey data with respect to response rates, representativeness, and nonresponse bias. Use the IDC NRBA App to answer questions such as:
What are our response rates and do they differ across subgroups?
Are some subgroups in the population overrepresented or underrepresented in our respondent data?
How do survey outcomes differ across subgroups?
Can statistical adjustments reduce nonresponse bias in our data?
The IDC NRBA App consists of three modules that guide the user though analysis and reporting.
Setup: Load a prepared data set(s) into the application
Analysis: Select and configure specific analyses to run, and view the results
Report: Export output tables summarizing the analyses into an Excel file
