Day 8: Independent t-Test

A t-test asks whether two means are significantly different. If the means, as representatives of two samples of the same variable, are equal or close to equal, the assumption is that the differences seen are due to chance. If the means are significantly different, the assumption is that the differences are due to the impact of an independent variable.
