1. A manager needs to compare the exact delivery costs from six suppliers. Which form of notation is most suitable?
A written description, because it explains each supplier in detail
A chart, because patterns in the data are clearer to see
An executive summary, because it summarises the main costs
A table, because exact values can be read and compared
2. A table lists the number of visits to each page but has no column headings. Why is this a problem?
Readers cannot tell what each column of figures means
The table holds less information than a chart
The figures in the table are no longer accurate
The table cannot be arranged into rows and columns
