• Quality assurance

    Your data-collection techniques must meet appropriate quality assurance standards. You need to address and document:

    • any limitations of the data source (for example, is the survey poorly designed, are there sampling errors and have these been articulated?)
    • any assumptions made
    • the approach taken and whether it is appropriate (for example, is the data- coding approach correct?).
