Student’s T Distribution – Confidence Intervals & Margin of Error

This statistics video tutorial provides a basic introduction into the student’s t-distribution. It explains how to construct confidence intervals around a population mean using the student’s t-distribution as well as calculating the margin of error or error bound of the mean. It’s a good indication to use the t-distribution as opposed to the normal distribution when the sample size is less than 30 and when you’re given the sample standard deviation instead of the population standard deviation.
