Introduction to Reasoning based DI

Reasoning-based Data Interpretation is a specialized form of data analysis used in management and competitive exams. Unlike traditional DI, which primarily involves numeric data, reasoning-based DI focuses on logical and analytical reasoning applied to a set of data or information. This type of DI assesses your ability to draw conclusions, make deductions, and analyze data in a logical manner.

Key Components of Reasoning-Based DI:

Data Scenario: Reasoning-based DI typically starts with a data scenario or a set of information, often presented in textual form.
Logical Questions: Following the data scenario, a series of logical questions or statements are provided. These questions require you to use deductive reasoning to arrive at the correct answers.

Interpreting Reasoning-Based DI:

Reasoning-based DI assesses your ability to analyze information critically, draw inferences, and make logical conclusions based on the given data scenario.

Example Reasoning-Based DI:

Let's consider an example reasoning-based DI scenario to illustrate these concepts:

Data Scenario: A company conducts interviews for four positions: Manager, Analyst, Programmer, and Designer. The following information is provided:

The Manager's interview is scheduled on Monday.
The Analyst's interview is scheduled on Wednesday.
The Programmer's interview is scheduled two days before the Designer's interview.
The Analyst's interview is not on Monday or Friday.

Logical Questions:

Q.1. On which day is the Programmer's interview scheduled?
Q.2. Which position's interview is scheduled on Friday?
Q.3. How many days are there between the Designer's and the Manager's interviews?

Answers:

Answer 1) The Programmer's interview is scheduled on Tuesday.
Answer 2)The Designer's interview is scheduled on Friday.
Answer 3) There are two days between the Designer's and the Manager's interviews (Tuesday and Wednesday).

Conclusion: Reasoning-Based Data Interpretation assesses your ability to analyze data through logical reasoning. It involves understanding the given information, making deductions, and answering questions based on that information. Regular practice with reasoning-based DI questions enhances your logical reasoning skills and improves your ability to draw conclusions from complex scenarios.
