8.5 Confidence Interval Using t-distribution for Matched-Pairs Design (Mean Difference of Sample 1 and Sample 2)

07/23/2016

This lesson on inferential statistics shows you how to calculate the Confidence Interval of the sample mean given a  matched-pair design. This test uses the t-distribution to estimate the population parameter.  In matched-pairs design, you are usually given 2 data set coming from a singe sample such as pretest and post-test or before the treatment and after the treatment experiment.

This lesson on inferential statistics shows you a complete procedure on how to compute for the confidence interval of the population mean using the t-distribution. The t-distribution is used when the population standard deviation is not given. You will only rely on the value of the mean and the standard deviation of the sample from a Normally distributed population
