Objectives

How to design surveys How to train interviewers What are call sheets? What are acceptable response

rates? Reporting relationships among

variables

Survey design

Online templates e.g. Zoomerang, Survey Monkey (free)

Statistical packages e.g. SPSS (costly)

Computer assisted data collection (automatic data analysis)
