In this study, the efficiency of Trimmed-t Test was examined to compare the samples of varying sizes
taken from populations with equal and unequal variances which were trimmed at different rates. The results of 10000
simulation test show that Trimmed-t Test would be used confidentially if the samples are equal in size and the
population variance is not known and/or it is not homogenous.
