Matched or Paired Samples T-Test – Hypothesis Testing

This Statistics video tutorial provides a basic introduction into matched or paired samples. It explains how to use the T-test and the student’s t-distribution to determine whether or not if you should reject the null hypothesis in favor of the alternative hypothesis. It also explains how to construct a confidence interval and calculate the margin of error at a specified significance level.
