Assignment Description
This group assignment draws upon the individual assignment and uses the same dataset used for the individual assignment [Global Corporation –Customer attributes &Sales data] to expand the analysis. You need to use Business Statistics tools, techniques and terminology that you have learnt, to analyse the data and to write up the assignment.
Similar to individual assignment, for the analysis you do not need to involve all the variables. However, given that there are new areas of analytics in this group assignment, prior to selecting variables you need to be clear about below:
 Considering variables available in the data, what are your assumptions about reasons that may cause satisfaction level to decrease?
 Based on the assumption you make in part a. what variables you believe that may be contributing to this satisfaction decline?
 Based on the choice of variables in part b., what are the analytical methods that you think you can employ to get some information from the provided dataset?
Using statistical theory, concepts, terminology and application and considering the dataset, as well as points a,b,c above create some research questions and answer them in a way that is meaningful to you. Accordingly, you will be able to write up the assignment. Research questions should be analysed and illustrated through use of graphs or charts or tables or a combination of all.
Assignment structure:
Further assumptions to the problem and business intelligence is required to conduct the following analysis.
Assignment structure:
 Introduction– Introduce the business problems. (10 marks)
 What are your reasons for the variables you choose for the analysis
 Binomial distribution (10 marks)
