1. You are carrying out market research on the use of public trans ort by rural households near a major city in your country. It has involved a long and quite complex questionnaire. Some 50 percent of the respondents completed the questionnaire on their own; the others were completed by researchers face-to-face with the respondents. The initial data cleaning is not going well and there is confusion about some of the responses in the questionnaires. You need to address the team
and explain what to look for and what to do. No one really understands the processes needed.

2. You are carrying out market research for your government on Internet use at home, while traveling, and at work. The problem is that you are using a wide variety of secondary data that has already been accumulated for other studies. This means the format of the data is different; some studies use the number of minutes, others use fractions of an hour, and still others use percentages of a 24-hour period or a 7-day week. What can be done to rectify the problem and make the data useable? Discuss this question with the analyst (a student in your class).
