Investigating Shopper Resistance to Self-Checkout Counters: A Data Analysis Study

A supermarket manager wanted to investigate the profile of shoppers resistant to the use of self-checkout counters available at the store he manages and to find out the reasons behind their resistance. He asks three of his staff to conduct a survey among customers using the store in Sheffield Hallam area during a quiet working day in October of 2019 as they exited the store. The short questionnaire used for the survey as well as the data collected can be found on an Excel file named “SCC”. There are two worksheets, one for the questionnaire used and the other worksheet for the raw data collected from the customers.

The data worksheet has 18 columns. Column A “Customer” is simply a column to identify the customer surveyed – Customer 1, Customer 2 etc… Each of the other 17 columns refer to a question – Column B refers to the gender question, Column C refers to the age question etc… The manager has employed you as data analyst to conduct this investigation. Your analysis should use the statistical facilities on Excel as required below. Required:

1.Label (show 5 rows) the codes for the categories of the following variables:

• Gender
• Age
• Education
• Are you a regular user of self-checkout Note to students:

There are FIVE tasks and you are expected to complete all of them. You are required to transfer the work of all tasks on to a single wordprocessed MS Word file and upload it on Turnitin, which is the submission of this assignment.

2.Produce frequency and percentage frequency tables (using Pivot tables) for each of the following variables:

• Gender
• Education
• Age
• SCC user
• Spending (£) For this last quantitative variable, the categories should be as follows: 140 3.

3.Draw the graphical representation for each of the following variables:

• Education (Pie chart)
• Age (Bar chart)
• Spending (Histogram) using the following categories: 140
• Spending (Box and whisker) graph

4.Consider now the variable “Spending (£)”.

Calculate the minimum, maximum, median, quartiles and the mean average statistics (show Excel formulas). Note: The tasks and all their requirements should be clearly separated (preferably each task starts on a separate page). All variables should be clearly named and their correct categories clearly labelled. Graphs should be appropriate and correctly labelled and each of them on the same page. Any calculations should be clearly presented and explained.

A plumber has decided to use the techniques of project management in order to plan a job.

He knew all the different activities of the job, their precedence and their average durations. They are shown on the table below. Draw a network diagram representing the sequence of activities and the dependence between them. Determine how long it will take to complete the job by conducting the forward pass By conducting the backward pass, identify the critical path and the noncritical path(s). Note: The work for this task should be produced using Word drawing facilities. The forward and backward passes should be clearly shown on the diagram. The calculations should be shown next to the network diagram.
