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. WebSTANDARD NORMAL DISTRIBUTION TABLE .

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. phillip lyndon

WebThe T-Distribution is a measure of probability (p-value). It is used to find the statistical significance when the sample size is small, i.e., less than 30, with an obscure standard deviation. The mean of a T-Distribution is evaluated as zero, and the variance is derived as v/ (v-2), where v is the degree of freedom.
