Types of GRE data interpretation questions

There are several types of data interpretation questions that can appear on the GRE test. Each type assesses your ability to analyse and draw conclusions from different forms of data. Here are some common types of data interpretation questions:

1. Bar graphs

Bar graphs present data using rectangular bars of varying lengths or heights. You may be asked to interpret the information presented in the graph, compare data across different categories or groups, calculate percentages or averages, or make inferences based on the data.

2. Line graphs

Line graphs display data points connected by lines, representing trends or patterns over time or other variables. Questions may require analysing the relationship between variables, identifying peaks or valleys in the data, predicting future values, or determining the rate of change.

3. Pie charts

Pie charts represent data as slices of a circle, with each slice representing a proportion or percentage of the whole. You may be asked to calculate proportions, compare different categories, identify the largest or smallest segment, or determine the change in proportions over time.

4. Tables

Tables organise data in rows and columns, presenting information in a structured format. You may need to extract information from the table, perform calculations, compare values, identify trends, or draw conclusions based on the data presented.

5. Scatterplots

Scatterplots use a grid to represent the relationship between two variables, with data points plotted as individual dots. Questions may require interpreting the correlation between variables, determining the strength of the relationship, identifying outliers, or predicting values based on the scatterplot.

6. Combination charts

Combination charts combine different types of graphs or charts within a single visual representation. You may need to analyse and interpret multiple sets of data, compare trends across different graphs, or draw conclusions by integrating information from various sources.

7. Data inference questions

In these questions, you are presented with a written passage that describes a data set or experiment. You must analyse the information in the passage and answer questions based on the provided data or draw conclusions from the passage.

8. Experimental design questions

These questions present a hypothetical research study or experiment and ask you to evaluate the experimental design, identify flaws or limitations, or predict the outcome based on the experimental setup.

Tips and strategies to master GRE data interpretation

Mastering GRE data interpretation requires a combination of knowledge, skills, and effective strategies. Here are some tips and strategies to help you excel in data interpretation on the GRE:

1. Understand the question types

Familiarise yourself with the different types of data interpretation questions that can appear on the GRE, such as bar graphs, line graphs, pie charts, tables, scatterplots, and combination charts. Understand the specific information each type presents and the common question formats associated with them.

2. Review and practise relevant maths concepts

Data interpretation questions often involve mathematical calculations, such as percentages, averages, ratios, and extrapolations. Review and strengthen your understanding of these mathematical concepts, as they form the foundation for accurate data analysis.

3. Interpret the visual data

When presented with a graph or chart, take time to carefully analyse the data it represents. Pay attention to labels, units of measurement, axes, and any additional information provided. Identify trends, patterns, and outliers within the data. Practice interpreting different types of visual data to enhance your proficiency.

4. Simplify and summarise

Simplify complex data sets by summarising the key information presented. Identify the main points, relationships, and comparisons within the data. Condensing the data in a concise and organised manner can help you better understand and approach the questions.

5. Focus on the question stem

Pay close attention to the question stem and understand exactly what it is asking. Identify the specific information or calculation required to answer the question. Highlight key keywords and phrases that guide your approach.

6. Work step-by-step

Break down the problem into smaller, manageable steps. Determine which calculations or operations are necessary to arrive at the answer. Perform one step at a time, ensuring accuracy and precision along the way. Avoid skipping or combining steps to minimise errors.

7. Estimate and approximate

Data interpretation questions often require quick calculations. Estimating or approximating values can help simplify complex calculations and save time. Round numbers to convenient values and use estimation to eliminate answer choices that are clearly too high or too low.

8. Use the process of elimination

When multiple answer choices are provided, use the process of elimination to narrow down the options. Cross out answers that are incorrect based on your analysis or calculations. This strategy increases your chances of selecting the correct answer.
