Question 2 This question related to a health survey; candidates seem passionate about the subject matter and provided some good discussion, which was pleasing. There were some good answers to part (i), but sometimes candidates did not give enough pertinent points to obtain full marks (or wrote extensively on one aspect). The advantages of collecting data using a diary were more extensively discussed than the disadvantages. Aspects such as the cost of executing a diary, its limitations in some population groups, and people’s unwillingness to participate in the first place, were seldom mentioned.
