Mathematics - Statistics
Practise 12 COMEDK previous year questions on Statistics, compiled from papers spanning 2014 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 COMEDK tests.
Statistics has been asked in 6 of the 15 years of COMEDK papers analysed (2012–2026), with 12 questions in all. 33% of them were easy, 67% moderate and 0% tough. Most of its questions came from 2025, with 4 questions that year. In the last three years (2024–2026) it had 9 questions across 9 papers, about 1 per paper.
The chapter's 4 topics are not weighted equally: Measures of Dispersion (8 questions, 67%), Statistics (2 questions, 17%), and Mean (1 question, 8%) have been asked the most. Measures of Dispersion has also led over the last five years, with 8 questions.

Statistics has appeared in 6 of the 15 years of COMEDK papers covered here, with 12 questions across 12 papers - about one per paper it appears in.
4.What is the difficulty level of Statistics questions in COMEDK?
Of the 12 questions analysed for this chapter, 33% are easy, 67% moderate and 0% tough. 2025 had the most, with 4 questions.
5.Which topics in Statistics should I focus on?
These topics have carried the most weightage in Statistics:
- Measures of Dispersion - 8 questions (67%)
- Statistics - 2 questions (17%)
- Mean - 1 question (8%)
6.Is Statistics's weightage in COMEDK going up or down?
Across all 12 papers analysed, Statistics has averaged about 1.0 questions per paper. In the last three years (2024–2026), that average has stayed about the same, at about 1.0 questions per paper. Use the year-wise numbers on this page for the exact trend before you decide how much time to give it.
