MST-004 IGNOU Handwritten Assignment 2026-27

Course Scope & Syllabus Overview for MST-004: Statistical Inference

MST-004: Statistical Inference is a core component of IGNOU’s Post-Graduate Diploma in Applied Statistics, designed to equip students with rigorous analytical tools for inferential reasoning in scientific research. This course bridges theoretical probability and empirical data analysis, emphasizing hypothesis validation, parameter estimation, and non-parametric methodologies. Through structured assignments and problem-solving exercises, learners develop proficiency in interpreting statistical models, assessing sampling distributions, and applying inferential techniques to real-world datasets. The curriculum aligns with the School of Sciences’ CBCS framework, ensuring alignment with contemporary research demands in natural, physical, and life sciences.

Key Syllabus Units & Topics

• Block-1 Sampling Distributions: Covers the foundational concepts of sampling theory, including central limit theorems, mean and variance of sampling distributions, and their applications in constructing confidence intervals for population parameters.
• Block-2 Estimation: Focuses on point and interval estimation techniques, such as maximum likelihood estimation, unbiased estimators, and the properties of estimators, with practical examples from experimental designs.
• Block-3 Testing of Hypothesis: Explores classical hypothesis testing frameworks, including Type I/II errors, p-values, and tests for means, variances, and proportions, with a focus on both parametric and non-parametric scenarios.
• Block-4 Non-Parametric Tests: Introduces distribution-free methods like the Mann-Whitney U test, Kruskal-Wallis test, and chi-square tests, essential for analyzing non-normal or ordinal data in scientific studies.
