“T-tests are used when you have two groups (e.g. males and females) or two sets of data (before and after), and you wish to compare the mean score on some continuous variable. There are two main types of t-tests. Paired sample t-tests (also called repeated measures) are used when you are interested in changes in scores for participants tested at Time 1, and then again at Time 2 (often after some intervention or event). The samples are ‘related’ because they are the same people tested each time. Independent sample t-tests are used when you have two different (independent) groups of people (males and females), and you are interested in comparing their scores. In this case, you collect information on only one occasion but from two different sets of people.” (Pallant 2011)
