Practise 4 JEE Advanced previous year questions on Statistics, compiled from papers spanning 2023 to 2026. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty JEE Advanced tests.
Statistics has been asked in 4 of the 27 years of JEE Advanced papers analysed (2000–2026), with 4 questions in all. 50% of them were easy, 25% moderate and 25% tough. Most of its questions came from 2026, with 1 question that year. In the last three years (2024–2026) it had 3 questions across 6 papers, about 0.5 per paper.
The chapter's 2 topics are not weighted equally: Measures of Dispersion (3 questions, 75%) and Mean (1 question, 25%) have been asked the most. Measures of Dispersion has also led over the last five years, with 3 questions. Measures of Dispersion has produced the most tough questions (1).
