Q10. When gathering information and data, it is important to test its reliability and validity. Basically, can you trust the information. You should discuss how you tested or veried the information and where you rejected information based on contradictions or ambiguity (Le. if looking at month by month statistics you noted one month was very low, it might have been due to the business experiencing a major event that resulted in having to close its doors for a week. The results for that month would have been quite different to other months and may be excluded from the review)
