What type of data must you collect to conduct a ttest? Why?

ttest 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 ttest and the data that is used? Please. Thank you.
