The Independent Samples t Test can only compare the means for two (and only two) groups. It cannot make comparisons among more than two groups. If you wish to compare the means across more than two groups, you will likely want to run an ANOVA. What is the main differences between an unpaired and paired t-test? Why would you want to limit the number of variables you are comparing? Why would you want to start with two groups and work...
