I am currently in the process of designing a survey on financial and billing information for the Indiana State Bar Association (ISBA). In preparation for this task, I have read and reviewed lots of surveys by bar associations in other jurisdictions. There are a surprising number, often conducted by local academics (I blogged about a really terrific survey of Pittsburgh lawyers here).
What I lack, however, is a good reference guide for interpreting survey data, particularly a methods book or article that discusses how to check for a representative sample and various weighting techniques for either correcting sample bias or imputing missing values based on known characteristics of the population (information I have because the survey is sponsored by the ISBA).
Any suggestions in the comments or by email would be greatly appreciated.
