SCATTERPLOTS WITH SURVEY DATA

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 asso ciated with the observations, imputed data for item nonresponse, and l arge sample sizes. Examples are given using data from the 1988 Nationa l Maternal Infant and Health Survey, the second National Health and Nu trition Examination Survey, and the epidemiologic follow-up of the fir st National Health and Nutrition Examination Survey.
