About IGNOU AST-01 — Statistical Techniques
AST-01 is a subject that teaches students how to collect, organise, analyse, and interpret data using standard statistical tools. You study descriptive statistics including mean and frequency distributions, probability distributions like Binomial and Poisson, sampling techniques, estimation, hypothesis testing through ANOVA and chi-square, correlation, and quality control using control charts.
Most students find probability and sampling the trickiest sections. That is because these require not just formula recall but understanding when to apply which method. Once you see a worked solution that explains the logic behind each step, these topics become far more manageable. Unnati Education's solved paper is written with that clarity in mind throughout.
AST-01 December 2025 — Question Paper Pattern and Marks Breakdown
Question 7 is fully compulsory and carries 10 marks across five sub-parts of 2 marks each. These test conceptual understanding through true or false statements with justification. From Questions 1 to 6, each carries 10 marks and you must attempt any four. Total marks are 50 and the exam runs for 2 hours. Here is the important part — calculators are not allowed, so all arithmetic must be done by hand. Choosing your four questions wisely based on topic strength is as important as knowing the methods themselves.
