Description of Two-sample t-test for the population mean The method used to compare the effectiveness of Virtual Reality Therapy (VRT) and Cognitive Processing Therapy (CPT) is Two-sample t-test for the population mean. The method is used to find out if the means of the two population are equal. The method can be applied in various cases and fields. For instance, in the field of engineering, the method can be used to determine if the new process is more efficient as compared to the previous process (Shi & Tao, 2009). In the field of interest, general psychology, the Two-sample t-test for the population mean has been used determine whether there is a difference is the number of weeks that a male military patient undergoing a VRT, a new but increasingly popular treatment for Post-traumatic stress disorder (PTSD), takes to recover, and the number of weeks a male military patient undergoing CPT takes to recover from PTSD.
