Describe how one feature of the study by Milgram (obedience) helped to make the study valid.
Dr Chand is going to measure how much adults want to participate in social activities, such as team sports or attending a festival.
Dr Chand wants to collect quantitative data about how much adults want to participate in social activities. He can use the methods of questionnaires or interviews.
Suggest two ways that Dr Chand could collect this data using one or both of these methods.

For one of the ways of collecting data you suggested in part (a):
Explain one way this method of collecting data is valid.
Explain one way this method of collecting data is not valid.
When Dr Chand conducts his study, he gives each adult a score out of 15 for how much they want to participate in social activities. He divides the adults into four different age groups and finds an average willingness to participate score for each group. These averages are shown in Table 8.1.
