functions, mathematical expectation and its properties, moments, moment
generating function, measures of central tendency, measures of dispersion,
skewness and kurtosis.
Concept of bivariate, marginal and conditional distributions, correlation
and regression for two variables, rank correlation, method of least squares and fitting of curves.
