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 … WebThe t-distribution can be formed by taking many samples (strictly, all possible samples) of the same size from a normal population. For each sample, the same statistic, called the t-statistic, which we will learn more about later, is calculated. The relative frequency distribution of these t-statistics is the t-distribution.
