Part 3: Data analysis questions
Question 1: Why is it important to record current and recent rainfall when sampling water quality?

Question 2: Did the digital recordings of the water quality parameters differ to the test strip recordings? Suggest reasons for any disparities and discuss how recording data using two methods would impact data reliability.
