Tabulation Concepts

Understanding the Concepts of Tabulation

Tabulation or a table chart is an easy way of organizing complex or large volumes of data across multiple categories or types and representing them together to draw valuable conclusions from them.

A table represents even a large amount of data in an engaging, easy to read, and coordinated manner. A table chart uses a set of data arranged in rows and columns.

The following are the important table charts concepts:

1. Speed Maths

Quicker calculation techniques are the key to solving any data interpretation question faster. A quick calculation can be mastered by working on 2 things:

1.1 Memory Based

There are a few things we need to know by heart to do the calculations faster, ex - Squares of numbers from 1 to 40, 20 x 20 multiplication table, etc.

For Example:

Squares of numbers from 1 to 40, 20 x 20 multiplication table, cubes of numbers from 1-12, powers of numbers from 2¹ to 2¹², etc.

1.2 Calculation Based Shortcuts

Few speed math techniques can be learned to perform calculations faster.

For Example:

2 x 2 multiplication, finding squares of numbers, finding square roots quickly, etc.

2. Averages

There are a few average-based questions asked in most of the tabulation sets, solve this effectively by adding the numbers and dividing them, and quick calculation of averages using approximation techniques will definitely help.

3. Percentages

There are specific percentage based questions asked in most of the tabulation sets, like 'what percentage of A is B', 'A% of B,' or 'percentage change'. To solve this effectively we need to be very good at calculating percentages.

4. Ratios

Some of the questions from the tabulation question sets are based on ratios. These can be easily solved using approximation techniques, divisibility tests, and a basic foundational understanding of ratios. Percentage concepts will also be a great help in solving tabulation question sets.
