I'm doing a (statistical) survey on whether or not international students at my college receive satisfactory grants. Here's the deal, I don't expect them to say yes it is satisfactory. I need a way to formulate questions to tricking them into giving me an accurate questions. I've already got my formalities written but how can I approach them with these questions? Bonus would be to tell how much more they would need (if at all).
In my opinion, test-retest method would be suitable to your request.
This procedure is quite simple: individuals are asked to take the test and then take the same test again at a later date. The scores are then compared. The closer the scores are, the more reliable the test.
This methodology is appropriate for instruments such as IQ tests and surveys because there is little chance of people experiencing a sudden jump in IQ or suddenly changing their opinions.
I wish i have been helpful.
