Hi there,
This is what I suggest to read graphs:
1. Read the graph
- Ask for one minute of time to understand the graph
- Summarize what the graph is about. Read in particular the graph title (often forgotten), the axes and the legend
2. Analyze the graph
- Repeat the question you have to answer. Many people don’t spend time to clarify the question they have to answer; consequently, they answer the wrong question. Don’t be one of them and be sure to restate what is the main insight you have to derive
- Provide an analysis related to the question. Analyze how the graph can help to answer the question you just repeated
3. Provide a conclusion for the graph.
- Answer to the question asked. Again, very often people simply state what the graph is about, without providing any conclusion. A great candidate will provide a clear answer based on data
- Present the next steps to follow. As a last step, a great candidate will present what should be done next to help further the client
In terms of material you can use the following to practice:
- Graphs in Casebooks
- Graphs in PST (you can download some for free from the McK website)
- GMAT Integrated Reasoning section
Hope this helps,
Francesco
