GRE Data Analysis Questions Type
The GRE Data Interpretation questions come in more than one form. Hence, it would be ideal to learn GRE data interpretation in GRE formulas. The GRE Data Interpretation will present information in any one of a number of visual formats. These include:
- pie charts
- bar charts
- line graphs
- scatterplots & best-fit lines
- box plots
- histograms
- charts of numerical data
Here are the different types of data that candidates will come across on the data analysis in GRE test.
Pie charts are mostly called circle graphs because they are circular charts divided into sectors. The sectors demonstrate percentages or proportions of a quantity that is defined in the question itself.
Example: The pie chart illustrates browser penetration among internet users across Europe.
Candidates can use this information to answer any question thrown at them. For instance, if the question asks you to find the number of Chrome users given that the total number of users is 1 million. Then you can simply use your knowledge of percentages, and say that the number of Chrome users is 15.5% of 1,000,000 = 155,000.
Column charts are also known as bar charts. A bar chart is a kind of visual illustration that has rectangular bars with lengths proportional to the values they represent. The bars can be plotted vertically or horizontally.
Example: In this graph, candidates can see how a bunch of countries compare when it comes to the number of oil reserves they hold. For instance, given that Venezuela has 300,000 million barrels of oil, and Iran has 150,000 million barrels. Then you can say that Venezuela has twice as much oil as Iran, or that the ratio of their oil reserves is 2:1. You may even be asked questions related to ratios, proportions, and percentages.
Line charts are usually shown on TV to compare the progress of two quantities.
Example: The GDP growth rates of two countries over time, or the performance of two stocks in the last quarter, and so on. Line graphs display the movement or growth of quantities.
Here is an example of a line graph
With such graphs, you will be asked questions like which year saw the maximum percentage change in share of voters. For the Democratic party, or the average percentage share of the voters for the Republican party from 1980 to 2010. You will be able to answer such questions easily if you are able to identify the data points correctly from the given line graphs.
Scatter plots are rarely seen on the GRE, compared to the other types of graphs that we discussed in this chapter so far. Scatter plots are useful to display bivariate data.
Example: age and weight of several persons on the same graph, or their annual income. Along with the amount of debt they carry, or their number of kids and number of cars, and so on.
For instance, a scatter plot may be used to show the number of hours studied by students In a university and the corresponding score in GRE Quant.
Using this graph, it is easy to answer any questions related to the information provided here. For example, you may be asked about the highest score in GRE quant among those who studied less than 30 hours.
