This article introduces the definition and characteristic of mathematical expectation and variance through the examples of Binomial Distribution,Poisson Distribution,Uniform Distribution,Exponential Distribution and Normal Distribution,the mathematical expectations and variances of these distributions are also introduced.The relationship of definitions,characteristics and independence between covariance and correlation coefficient are discussed.Then the article introduces the definition,characteristic and use in daily life of Conditional Mathematical Expectation.At last with the type of matrix the article describes the mathematical expectation,variance and the degree of correlation between them,it also explains the characteristics of them.
