Scatterplots with Survey Data

Abstract

We suggest various modifications to make scatterplots more informative when used with data obtained from a sample survey. Aspects of survey data leading to the plot modifications include the sample weights associated with the observations, imputed data for item nonresponse, and large sample sizes. Examples are given using data from the 1988 National Maternal Infant and Health Survey, the second National Health and Nutrition Examination Survey, and the epidemiologic follow-up of the first National Health and Nutrition Examination Survey
