Practise 75 TS EAMCET previous year questions on Statistics, compiled from papers spanning 2009 to 2025. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty TS EAMCET tests.

Statistics has been asked in 13 of the 24 years of TS EAMCET papers analysed (2001–2024), with 75 questions in all. 59% of them were easy, 33% moderate and 8% tough. Most of its questions came from 2020, with 17 questions that year. In the last three years (2022–2024) it had 17 questions across 17 papers, about 1 per paper.

The chapter's 6 topics are not weighted equally: Measures of Dispersion (54 questions, 72%), Relation Between Variance and Mean Deviation (11 questions, 15%), and Mean Square Deviation (5 questions, 7%) have been asked the most. Measures of Dispersion has also led over the last five years, with 18 questions. Measures of Dispersion has produced the most tough questions (5).

3.Is Statistics an important chapter for TS EAMCET Mathematics?

Statistics has appeared in 14 of the 25 years of TS EAMCET papers covered here, with 75 questions across 50 papers - about 2 per paper it appears in.

4.What is the difficulty level of Statistics questions in TS EAMCET?

Of the 75 questions analysed for this chapter, 59% are easy, 33% moderate and 8% tough. 2020 had the most, with 17 questions.

5.Which topics in Statistics should I focus on?

These topics have carried the most weightage in Statistics:

  • Measures of Dispersion - 54 questions (72%)
  • Relation Between Variance and Mean Deviation - 11 questions (15%)
  • Mean Square Deviation - 5 questions (7%)
