The dataset is also available on Moodle under the Assignment folder. 1.1 Use the dataset to answer the following questions. 20 a) How many observations are there in the dataset? What is the 4^(th ) observation? b) Indicate the scale of measurement for each variable in the dataset. c) For each variable indicate whether it is quantitative or qualitative. d) For quantitative variables, indicate whether they are continuous or discrete. e) Is the dataset time series, cross sectional or longitudinal? Motivate. 1.2 Use the dataset to construct and interpret the following graphical and tabular summaries a) Pie chart to show the sales distribution for the different regions. b) Frequency distribution to show the total number of units bought for each item. c) Cumulative frequency distribution graph (O'give) for the sales amount. d) Tabular representation/summary to show the relationship between salesman and sales amount. e) What insight can be gained from the tabular and graphical representations above?
