what are the goals of survey research design
to produce accurate, credible, and replicable data in cost-effective and timely ways.
what are the trade-offs between high response rate and lower costs
- set realistic and reasonable expectations about error levels
- set affordable and feasible budget goals
- don’t chase insignificant improvement in response rate at a high cost
- keep total design in mind
what does total design refer to
keep in mind the survey process from the very beginning to the very end
