Probability

This chapter features measures of dispersion. We will discuss range, coefficient of variation, and mean deviation in detail. Computing variance and standard deviation of ungrouped or grouped data is also discussed.

This chapter introduces students to the concept of probability. They will understand random experiments and events alongside addition theorem of probability. Conditional probability, multiplication theorem, and Bayes' theorem are also identified here.

This chapter focuses on random variables and probability distributions. Here, we will understand the definition of random variables. Theoretical discrete distributions like binomial and Poisson distributions are also discussed here.
