In the process of examining the relationship between variables, researchers can use t test or ANOVA to compare the means of two groups on the dependent variable (Green & Salkind, 2012). The main difference between t-test and ANOVA is that t test can only be used to compare two groups while ANOVA can be used to compare two or more groups. In the process of selecting the data analysis technique for this study, I considered both ANOVA and t-test. The advantage ANOVA has over t-test is that the post-hoc tests of ANOVA allow to better controlling type 1 error (Hopkins, 2000). Therefore, in order to control type 1 error, I chose ANOVA as data analysis technique for this study.
