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.
