Here we provide the details of some of the numeric results we have obtained regarding the factors that affect the reliability of measurement in surveys. Results are provided for a wide range of issues involving the design of methods of estimating reliability, and the role of various factors, including question attributes, that influence levels of measurement error.
The following is a list of these special topics, which present results that can help us understand the factors related to reliability of survey measurement. Click on the titles below to provide access to a relevant pdf document.
