What should I include in the introduction to get excellence?
AS91263: Design a Questionnaire is marked holistically. This means that you must be able to show statistical insight throughout your report. This includes weaving the research you have done throughout your report, thinking about how this questionnaire meets your research objectives, any limitations this questionnaire may have and/or how the results could be used in practice.
You might find this sample report useful - just be mindful that this is considered a “low Excellence,” so it is the minimum an Excellence-level student would be expected to submit.
Best of luck in with your questionnaire assessment!
