The independent-samples t-Test is appropriate when there are two independent groups and the researcher wants to compare the means of a continuous outcome variable between them. In this case, the clients in Group A and Group B are not connected to each other and have been randomly assigned, so the independent-samples t-Test is the best choice. The one-sample t-Test would be appropriate if comparing the mean of one group to a known population mean, the paired-samples t-Test would be appropriate if comparing two related groups (e.g., clients before and after treatment), and the independent-samples t-Test with change scores would be appropriate if comparing the change in scores between two groups, rather than the raw means.
