GATE 2025 Statistics (ST) Question Paper PDF Download

For students aiming to master the field of data analysis and statistical theory, practicing with the official GATE 2025 Statistics (ST) question paper is a vital step. Released by the organizing institute, IIT Roorkee, this document represents the standard for the 2025 examination. By analyzing the questions posed in this paper, you gain direct insight into the weightage of topics such as Probability, Calculus, and Multivariate Analysis, allowing you to refine your study approach for upcoming cycles.

Why You Need to Review the 2025 Statistics Paper

The GATE 2025 Statistics paper is designed to test not just rote memorization, but the application of complex statistical concepts. Reviewing this paper helps you understand the shift in difficulty levels and the specific framing of questions that modern examiners prefer.

Statistics is a subject that demands both mathematical rigor and analytical thinking. Whether you are preparing for M.Sc./Ph.D. admissions or looking for opportunities in public sector undertakings (PSUs), this paper is the most accurate reflection of the current testing standards. Using this document alongside the official answer key provided by IIT Roorkee ensures that your self-assessment is based on the final, validated solutions.

GATE 2025 Statistics Exam Pattern

Understanding the structure of the ST paper is essential for effective time management. The 2025 exam followed a consistent pattern:

• General Aptitude: 15 Marks (Mandatory)
• Core Statistics Subject: 85 Marks
• Total: 100 Marks

You had exactly 3 hours to complete the 65 questions. Unlike many engineering papers, the Statistics (ST) paper does not include a separate "Engineering Mathematics" section; rather, mathematical and statistical concepts are integrated directly into the 85 marks of the core subject section.

Types of Questions

The GATE 2025 Statistics paper utilizes three specific formats:

• Multiple Choice Questions (MCQs): These feature four options with only one correct answer. Negative marking is applied here: 1/3 mark is deducted for a 1-mark question, and 2/3 mark is deducted for a 2-mark question.
• Multiple Select Questions (MSQs): These provide four options, and one or more can be correct. You must select all correct options to receive full marks. There is no partial marking and no negative marking for these questions.
• Numerical Answer Type (NAT): These require you to input a specific numerical value using a virtual keyboard. There is no negative marking for these, making them excellent opportunities to secure points if your calculation is precise.

Key Topics and Weightage

Based on the 2025 exam trends, certain areas carry significantly more weight. If you are planning your revision, focus your energy here:

• Probability: Typically the highest weightage topic (approx. 20%). It serves as the foundation for almost every other section.
• Calculus: Roughly 15% of the paper. This includes integral and differential calculus as applied to statistical distributions.
• Multivariate Analysis: A critical area (approx. 10%) for advanced statistical inference.
• Other Core Areas: Matrix Theory, Stochastic Processes, Estimation, Testing of Hypotheses, Non-parametric Statistics, and Regression Analysis each contribute roughly 8-10% to your total score.

How to Analyze Your Performance

To get the most value out of this document, follow this structured review process:

1. Timed Simulation: If you are using this as a practice test, set a 3-hour timer. Avoid checking the answer key until you have finished the entire paper.
2. Error Categorization: After checking your answers, categorize your mistakes. Was it a conceptual gap? A calculation error? Or a failure to identify the correct options in an MSQ?
3. Use the Master Key: Always compare your responses against the Master Question Paper and Final Answer Key released by IIT Roorkee. This is the only source that guarantees accuracy.
4. Practice the Virtual Calculator: Many NAT questions involve complex calculations. Ensure you are proficient with the GATE virtual calculator interface, as it is your only tool during the actual exam.
