f(x)|f x	Probability density function (pdf) of random variable X
μ x	Mean value for the random variable X
${\sigma }_x=\sigma /\sqrt{N_x}$	Standard deviation for the random variable X
$\overline{x}$	Mean value of the samples belonging to random variable X
σ	Standard deviation of the samples belonging to random variable X
v	v=N x−1 Degree of freedom of t-distribution
