Performance of some parametric test statistics for testing the difference of means of two skewed populations

Right skewed data is available in the field of health science, biological science, epidemiological science and others. This paper assessed some existing procedures for testing the difference of means of two right skewed populations. A Monte Carlo simulation study has been conducted to compare the performance of the test statistics in the sense of empirical size and power of the selected tests. Based on the simulation study results, some good test statistics are recommended for practitioners. A real life health related example has been considered to illustrate the application of the techniques.
