There are often questions in a survey that allow respondents to pick more than one answer. The very first question on the alcohol survey, for example, asks respondents whether they have watched television, read a newspaper, read a magazine, listened to the radio or used the Internet in the last seven days. Respondents can reply ‘Yes’ to as many of these that apply. For the purpose of analysis, each medium will need to be treated as a separate variable, each one of which is either selected or not selected (so, it is binary). The five items then need to be analysed together. The results are shown in Figure 2.12. This indicates that there were 3,418 yeses. The 909 who indicated that they watched television constituted 26.6 per cent of the 3,418 yeses and 98.9 per cent of the 920 cases. Box 2.5 explains how to do this in SPSS.
