Need practice with two-sample t-tests? Use the questions, datasets, and answers provided below to fine-tune your skills.
DISCLAIMER: I made these practice questions and answers in (somewhat) of a rush, and there may be some mistakes. Also, I made them with Excel in mind. If you are using SPSS or a different stats package, you may obtain slightly different results. PLEASE email me if you notice any mistakes – particularly with the answers to the questions.
