Why Use the Independent Simple t-test?
The t-test is generally used when there are two study groups, an experimental group and a control group, or for a pre- and post-test over the same group when there are more than 30 subjects in the sample. In selecting the appropriate statistical test, the researcher must verify that the data pass all of the assumptions that are required for the test. In the present study, the data pass all assumptions that are required to use the independent simple t-test to find valid results. The ANOVA test is recommended for two or more independent groups, but the simple t-test is suggested when there are only two groups: a control group and an experimental group
