Independent Samples T-Test

Independent Samples and Paired Samples T-Tests tell you if the means of two groups are significantly different or not. T-Tests can be applied to data that is normally distributed and when the data in each group come from different participants or when each participant provides a data point to both groups. This video demonstrates how to perform the first of these comparisons - when each group is comprised of different participants, hence the name: Independent Samples T-Test.
