The t-distribution is a type of normal distribution that is used for smaller sample sizes. Normally-distributed data form a bell shape when plotted on a graph, with more observations near the mean and fewer observations in the tails. The t-distribution is used when data are approximately normally distributed, which … See more As the degrees of freedom (total number of observations minus 1) increases, the t-distribution will get closer and closer to matching the standard normal distribution, a.k.a. the z-distribution, until they are almost identical. … See more A t-score is the number of standard deviations from the mean in a t-distribution. You can typically look up at-score in at-table, or by using an online t-score calculator. In … See more WebThe essential uses for the t distribution are for finding: P-values for t-tests when testing the mean and for the coefficients in regression analysis. Critical values that define the upper …
