standard normal is for a lot of data, a t distribution is more appropriate for smaller samples, extrapolating to a larger set.

Actually the normal distribution is the sub form of Gaussian distribution.Gaussian distribution have 2 parameters, mean and variance.When there is zero mean and unit variance the Gaussian distribution becomes normal other wise it is pronounced as Gaussian.Wrong! The standard normal distribution has mean 0 and variance 1, but a normal distribution is the same as the Gaussiand, and can have any mean and variance.

The normal distribution would be a standard normal distribution if it had a mean of 0 and standard deviation of 1.

A mathematical definition of a standard normal distribution is given in the related link. A standard normal distribution is a normal distribution with a mean of 0 and a variance of 1.

When its probability distribution the standard normal distribution.
