What type of data must you collect to conduct a t-test? Why?

1. PsyDAG

t-test is similar to Z, but uses a correction to make up for smaller size of a sample, especially less than 30. With smaller samples, they are less likely to be normally distributed.

Can you send me to the right website to find information on t-test and the data that is used? Please. Thank you.
