The following chart summarizes the complaints received at a catalogue sales call centre by day of the week. The chart shows percentages for each day. The complaints are classified as related to delivery (the order has not arrived), fulfilment (an item was missing from an order or not what was ordered), size (an item did not fit), and damage. Discuss: (a) Is the day of the week associated with the nature of the complaint? Explain why you think that these variables are or are not associated. (b) What supplemental information that is not shown by the chart is important to managers in charge of dealing with complaints?
