The JEE Main exam is conducted by the National Testing Agency (NTA) for admission to undergraduate engineering programs in prestigious Indian institutions like the Indian Institutes of Technology (IITs), National Institutes of Technology (NITs), and other centrally funded technical institutions. The mathematics section of the JEE Main exam covers a wide range of topics, including mathematical statistics.


Mathematical statistics is an important branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of data. It involves various statistical concepts and methods. In the JEE Main exam, questions related to mathematical statistics may appear under the statistics and probability section. Some of the key topics covered include:

• Measures of central tendency (mean, median, mode)


• Measures of dispersion (variance, standard deviation)


• Probability distributions (binomial, Poisson, normal)


• Sampling theory and estimation


• Hypothesis testing

In the mathematics section of the JEE Main exam, questions related to mathematical statistics can be of various types. Some common question patterns include:

• Calculating mean, median, mode, variance, or standard deviation of a given data set


• Applying probability concepts to solve problems


• Using probability distributions to find probabilities or expected values


• Applying sampling theory to estimate population parameters


• Solving hypothesis testing problems based on given data

Mathematical statistics is an essential topic for aspiring engineers as it helps in understanding and analyzing real-world data, making informed decisions, and solving problems related to quality control, experimental design, and data analysis. It provides a strong foundation for statistical analysis, which is crucial in various fields of engineering and scientific research.


To excel in mathematical statistics and other topics covered in the mathematics section of the JEE Main exam, it is important to have a clear understanding of the concepts and practice solving a variety of problems. Candidates should refer to the JEE Main syllabus and study materials provided by reputable sources such as NCERT textbooks, reference books, and online platforms like EduRev to enhance their preparation.


While mathematical statistics is an integral part of the mathematics section in the JEE Main exam, it is important to note that the weightage of questions from this topic may vary from year to year. Therefore, candidates should focus on all the topics mentioned in the JEE Main syllabus and prepare thoroughly to maximize their chances of success in the examination.
