There are numerous types of tables that display numerical data. Numerical reasoning tests tend to contain a mixture of table themes - population demographics, balance sheets, results of telemarketing surveys, etc. - since the administrators' intention is to see how quick you can analyse shifting sets of data. Here are some popular tables used at numerical reasoning tests. We advise you to go through these examples and then start practicing.
This table is quite simple. Numerical figures do not represent millions or thousands, but rather absolute numbers, and there are no columns that include percentages or ratios. After using the orientation test - setting your eyes at a specific point within the data range and making sure you can understand the context - it is clear that the "Total" column is the sum of "All countries"+ "UK citizens".
→ A common question might be:
"What is the percentage-point-increase of non UK, non Chinese students' relative participation between 2010 and 2011?"
Here is another popular table, presenting demographic statistics:
→ A possible question might provide you with data about the net migration in Poland, which is -0.47 (migrants per 1000 people), and then ask you to calculate Poland's population growth rate.
The following table displays the results of an experiment. It is packed with figures, and the asterisks would probably be crucial for answering certain questions.
→ A tricky question might be:
"What is the % difference of weighted vocabulary success rates between the two age groups of experiments 1,2, combined?"
In these tables you would probably be asked to calculate some popular financial ratios - profit margins, growth rates, return on equity, etc.
Simpler cases might include the tables we come across with on a daily basis, e.g. nutritional values of foods, bills, travel expenses reports, etc.
*% Daily values are based on a 2000 calorie diet
→ This table might introduce the following question:
"How many grams of the above product must a person with a daily diet of 2400 calories eat to retain his full daily Calcium intake?"
