Why Data Interpretation matters in CAT

CAT DI is often mixed with reasoning, so the data alone may not give the answer. You must first work out the missing values from the given conditions.

Key data interpretation concepts

• Percentage change and percentage share
• Ratios and comparisons across categories
• Averages and weighted averages
• Approximation to separate close options

Important formulas

Common mistakes

• Calculating exactly when the options are far enough apart to approximate.
• Misreading units or the base year in a table.
• Ignoring footnotes and conditions that change how the data should be read.

Practical solving approaches

• Spend the first minute understanding what each row, column and axis represents.
• Write the missing values into the table before you start the questions.
• Round sensibly and check whether the options can be separated with estimates.

Data Interpretation FAQs

Do I need fast calculation for DI?

Comfortable mental arithmetic helps, but working out the structure of the set and approximating well matter more than raw speed.
