Quick Tips for Data Interpretation
In gleaning data from a chart, graph or table, it's remarkably easy to inadvertently grab your data from the wrong graph, bar, line, etc. This is the #1 cause of incorrect responses in CAT Data Interpretation. To avoid this blunder, point your finger/pencil to the data you want; put your finger/pencil directly against the question paper and keep it there until you're sure you're looking at the right part of the right chart or graph.
Check to see if the question asks for an approximation. If so, you can safely estimate numbers by rounding off.
CAUTION:
1. When rounding off fractions, round the numerator and denominator in the same direction (either up or down); otherwise you'll distort the value of the fraction.
2. Don't confuse percentages with raw numbers. Always ask yourself which type of number the chart or graph is providing, and which type the question is asking for.
3. It's okay to rely on visual approximations when it comes to reading bar graphs and line charts. The test-makers are not out to test your eyesight. So if two or more answer choices come very, very close to your solution, rest assured that you needn't estimate values more precisely.
Take 15-30 seconds right up front to assimilate and make sense of the chart, graph, or table and be sure to read all the information around it. Get a sense for what the variables are and how they relate to one another, before you tackle the questions.
Hope it helps you out..
