Hi,

You can use the following approach:

1. Take a minute to look at the graph
2. Read the graph title
3. Look at the graph type and define the type (pie chart, line chart, etc)
4. Look at the legend (ask for clarifying questions if necessary)
5. Identify whats going on on the graph. Look for: Trends, % structures,
6. Look for unusual things (consultants love to integrate these traps in charts) - correlations, outliers, etc
7. Make 3-4 conclusions from the graph. Think of potential hypothesis on what could be the root cause / what are the consequences
8. Prioritize the most important for your current analysis and move forward with the case

Sources to learn from (prioritized):

1. Study "Say it with Charts" book
2. Learn basic statistics (Any GMAT or MBA prep guides)
3. Check all available MBB presentations and publications. Practice to derive conclusions and check yourself with the actual ones from the article / presentation
4. GMAT IR part (Official guide and Manhattan prep)
5. "Consulting Bible" and "Vault guide for consulting" - check the chapters on cases with graphs in these books

Good luck!

Hi Anonymous,

Vlad already mentioned several resources you can use for self-preparation. In terms of the general approach, you can structure a graph analysis considering the following steps:

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 main question you have to answer. Many people don’t spend time to clarify the specific 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. Once you have a clear understanding of the graph, then, and only then, you can move to an analysis of how the graph can answer the question you have 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 connection between the analysis done and the previous question formulated, with a clear summary of the whole analysis
• Present the next steps to follow based on such conclusion. As a last step, a great candidate will present what can be done next to help further the client on the particular question raised.

Hope this helps,

Francesco

Hi Anonymous,

For general advice how to improve graph reading, the GMAT chapter for integrated reasoning is a good ressource (I believe it was added 2012 or 2013 to the GMAT, so you can take any GMAT ressource after that period).

Hope that helps - if so, please be so kind to give it a thumbs-up with the green upvote button below!

Only thing I have to add to Vlad's comment is that the practice materials for the McKinsey PST and BCG Potential test can also definitely help.

Dear A,

The structure and the process itself for beter analysing was nicely explained by Francessco. What I can add here is thet you just have to practice keeing in mind that mechanism until you start making it automatically.

Best,

Hello!

I would practice leveraging GMAT.

GMAT unfortunately only gets better with practicing. Good news is that there are many ways of doing so!

There are free exams in the internet that you can use for practice (the one of LBS MBA page, Verits prep, as well as some free trials for courses such as the one of The Economist (https://gmat.economist.com/)

Hope it helps!

Cheers,

Clara
