WebThe normal distribution assumes that the population standard deviation is known. The t- distribution does not make this assumption. The t- distribution is defined by the degrees of freedom. These are related to the sample size. The t- distribution is most useful for small sample sizes, when the population standard deviation is not known, or both.
