A brief non-technical introduction to the t distribution, how it relates to the standard normal distribution, and how it is used in inference for the mean.
In this video, you will learn how to calculate probabilities and find quantiles (or critical values) for the student t distribution. We will present the pt, dt and qt ...
The t-distribution, also known as the student's t-distribution, is used when making inferences about a population mean when the population standard deviation is ...

An introduction to the t distribution, a common continuous probability distribution. I discuss how the t distribution arises, its pdf, its mean and variance, and its ...
Here we will demonstrate visually how power is calculated for a one-sided, one-sample T-test. We will assume that the data follow a normal distribution with ...
