The t -distribution, also known as Student’s t -distribution, is a way of describing data that follow a bell curve when plotted on a graph, with the greatest number of observations close to the mean and fewer observations in the tails. It is a type of normal distribution used for smaller sample sizes, where the … See more 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 … 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 … 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 … See more WebMar 26, 2016 · As the degrees of freedom increases, the area in the tails of the t-distribution decreases while the area near the center increases. (The tails consist of the extreme values of the distribution, both negative and positive.) Eventually, when the degrees of freedom reaches 30 or more, the t-distribution and the standard normal …
