Basic concepts and common notation of classical statistics.

collection MATH of independent and identically distributed (iid) random variables with distribution $f\left( x\right) $ is called a random sample from population $f\left( x\right) $ .

Let MATH be a real valued function whose domain includes the sample space of MATH . The random variable MATH is called "statistic".

Sample mean and variance are MATH , MATH

The following identity is useful MATH for any numbers $x_{1},...,x_{2}.$

For any sample MATH of population with mean $\mu$ and finite variance $\sigma^{2},$ the sample mean and variance have the properties MATH .
