If you are treating a survey like a quantitative input, you can only ask questions that the respondents can be relied on to count. You must be honest about the type of data you are able to collect, or don’t bother.
To write a good survey. You need to be very clear on what you want to know and why a survey is the right way to get that information. And then you have to write very clear questions.
But you have to ask, what are you quantifying? Is it an actual quantity of something, e.g. how many, how often — or is it a stealth quality like appeal, ease, or appropriateness, trying to pass itself off as something measurable?
