Which of these purposes does not pertain to charts?

The correct answer is Option (2) → Selecting value

Charts present data visually so that it can be understood at a glance: they are used to compare values, to see trends over time and to recognise patterns in the data. Selecting a value is done in the worksheet; it is not a purpose of a chart.

Option (1) Making Comparisons — A purpose of charts. Bars and columns make values easy to compare.

Option (2) Selecting value — Correct. It does not pertain to charts.

Option (3) Identifying trends — A purpose of charts. A line chart shows the trend in data over time.

Option (4) Recognising Patterns — A purpose of charts. Patterns that are hard to see in numbers stand out in a chart.
