The GATE 2025 Statistics has over 200 subtopics covering main areas like Calculus, Matrix Theory, Probability, Distributions, Stochastic Processes, Estimation, and Regression Analysis.

From previous exams, topics such as Probability and Distributions accounted for roughly 15–20% of the questions, emphasizing their significance in preparation. In the GATE 2023 exam, about 30% of the questions focused on convergence theorems and hypothesis testing, indicating which subjects are often prioritized.

Calculus, which includes sequences, series, and integration, makes up about 10–15% of the exam. The Matrix Theory section includes topics like rank, eigenvalues, and eigenvectors and contributed to about 12% of the questions in the GATE 2024 exam. Common distributions, such as Poisson, Binomial, and Normal, accounted for roughly 25% of questions in previous years, making them key areas to focus on.

Stochastic Processes, which include topics like Markov chains, usually make up 5–10% of the exam. Estimation and Hypothesis Testing are important too, covering about 20–25% of the questions. Past exam data shows that 80% of top students spent more than 300 hours studying complex topics like multivariate analysis and regression.

Here is a detailed article for GATE 2025 Statistics Syllabus to help students prepare for the GATE 2025 Statistics exam.
