Nonparametric Methods for IIT JAM and GATE Statistics

Preparing for competitive statistics exams requires a deep, intuitive understanding of distribution-free methods. This comprehensive text-based course guides you through the core concepts of nonparametric hypothesis testing, tailored specifically for the rigorous demands of graduate-level statistics syllabi. You will transition from memorizing formulas to deeply understanding the theory, assumptions, and mathematical derivations behind nonparametric tests, gaining the confidence to solve complex exam-style problems and analyze data with precision. What you'll learn: Understand the foundational differences between parametric and nonparametric statistical frameworks; Master classical single-sample and two-sample tests, including the Sign Test, Wilcoxon Signed-Rank, and Mann-Whitney U tests; Apply multi-sample and association tests such as the Kruskal-Wallis test, Friedman test, and run tests for randomness; Derive test statistics, asymptotic distributions, and power efficiencies under various hypotheses; Explore modern computational resampling techniques like basic bootstrapping to complement classical asymptotic theory; Solve rigorous practice problems designed to mirror the format and difficulty of competitive entrance exams. The course starts with foundational definitions of order statistics and distribution-free properties before advancing to specific hypothesis tests, mathematical proofs, and exam-focused problem-solving strategies. This course is designed for undergraduate students and exam aspirants; no prior exposure to nonparametric methods is required, though a basic understanding of introductory probability and parametric inference is recommended.
