tdistribution is also known as student's tdistribution .....
this is a probability distribution that is used to estimate the population parameter when the given sample space is small or when the variance is unknown .
this type of distribution has three types of properties and they are:

mean distribution is equal to zero

variance is equal to v/ (v2) where the v is the degrees of freedom and v is always less than 2
 the variance is always greater than one. with infinite degrees of freedom the tdistribution is same as standard normal distribution.
