Our data show that the mean translation time for human translators (n = 15) was 46.27 min (SD = 13.00), and it was 41.03 min (SD = 13.02) for the post-editors (n = 15). Nevertheless, the independent samples t-test showed that the difference between the two groups was not significant (t(28) = 1.09, p = .28).

As there were language proficiency differences, albeit not significant, between B English and C English students, the question arose whether the time taken to complete the tasks was different for these two groups. Independent samples t-tests showed no significant differences either in the HT (B English (n = 6): M = 45.22 min, SD = 9.53; C English (n= 9): M = 46.94, SD = 15.43, t(13) = –0.24, p = .817) or in the PE condition (B English (n = 6): M = 38.54, SD = 9.27; C English (n = 9): M =42.69, SD = 15.61, t(13) = –0.58, p = .57). Nevertheless, there is a tendency for C English students to work somewhat slower than B English students.
