Your analysis should use the statistical facilities on Excel as required below. Required: 1. Label the codes for the categories of the following variables: • Gender • Age • Education • Are you a regular user of self-checkout user Note to students: There are FOUR 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. The deadline for this assignment is 2. Produce frequency and percentage frequency tables for each of the following variables: • Gender • Education • Age • SCC user • Spending (£) For this last quantitative variable, the categories should be as follows: <100 100- 109 110- 119 120- 129 130- 140 >140 3. Draw the graphical representation for each of the following variables: • Education (Pie chart) • Age (Bar chart) • Spending (Histogram) using the following categories: <100 100- 109 110- 119 120- 129 130- 140 >140 • Spending (Box and whisker) graph 4. Consider now the variable “Spending (£)”. • Calculate the minimum, maximum, median, quartiles and the mean average statistics. • Calculate the mean and standard deviation” split by users (and non-users) of SCC. 5. Produce a cross-table between each of the following two variables and draw an appropriate multiple bar chart: • Are you a regular user of self-checkout user and Gender • Are you a regular user of self-checkout user and Age 6.
