To learn more about these two types of study design where the independent-samples t-test can be used, see the examples below:Note 1: An independent-samples t-test can also be used to determine if there is a mean difference between two change scores (also known as gain scores). However,...
Output I - Significance LevelsAs previously discussed, each dependent variable has 2 lines of results. Which line to report depends on Levene’s test because our sample sizes are not (roughly) equal:if Levene’s test “Sig” or p≥ .05, then report the “Equal variances assumed” t-test...
test (SPSS version 9.0). The criterion of significance was set atIn 1987, a child with Fanconi's anaemia received an allogeneic transplant using the cryopreserved umbilical cord blood (UCB). As a result, the potential of UCB as a source of haemopoietic stem cells for transplantation rapidly ...

Paired Samples T-Test Assumptions Technically, a paired samples t-test is equivalent to a one sample t-test on difference scores. It therefore requires the same 2 assumptions. These are independent observations; normality: the difference scores must be normally distributed in the population. Normalit...
