Data Analysis
Data analysis questions are the least frequent, but there are enough of
them to merit a separate tutorial. The data analysis questions are very
consistent. They ask you to understand a visual presentation of data. The
presentation is commonly a pie chart, a bar chart, a line chart or a
table. The questions ask you to identify trends, find a maximum or minimum,
calculate proportions, calculate percentage change, calculate averages,
etc.. These calculations should all be relatively simple and familiar; the
challenge is in finding the data that you need from the table or graph.
