Methods of validating questionnaire

Examples of non-testable research questions are: What do customers feel is fair price for the new product? How do customers feel about the quality of our products?

What are employee's attitudes towards the new management? Respondents' answers to these questions can be summarized in descriptive tables and the results might be extremely valuable to administrators and planners.

How can we determine if a survey is actually measuring what it's supposed to measure?

There is a significant difference between the level of male and female satisfaction with the service.There is no significant difference between the level of male and female satisfaction with the service.There is no significant relationship between managerial level and support of the new budget.For example, imagine that we've done our survey, and now we need to decide what constitutes satisfactory service? There is no exact cutoff point where we would say "yes" our customers are satisfied, or "no" they are not.When we ask questions like this, it's important to establish a decision making guideline before doing the survey.
