(a) A retail chain has 5 stores: A, B, C, D and E in a city. The average number of sales transactions (sales volume) based on a random sample has been calculated for three periods during the day (morning, afternoon and evening). The retailer conducts a two-way analysis of variance to investigate whether there appears to be a difference in the average number of sales transactions in different stores and at different times of the day. Analyse the selected SPSS output in Figure 1 (spread over the next two pages) and discuss what conclusions can be drawn from the data. In your analysis, be sure to address at least the following: • Describe the strength of the joint effect of the factors. Test the significance of the variables individually and the interaction between them. • Describe the pattern of interaction. (20 marks) (b) Discuss the reasons for the frequent use of cross-tabulations in market research. What are some of the limitations? Give two examples of cross-tabulations you might expect to find in a market research study. (10 marks) (a) A retail chain has 5 stores: A, B, C, D and E in a city.
