q2 · i? · causal · r1

Descriptive comparison of the 3 of 9 control participants who completed the posttest in the same study; the article states "we did not compute significance levels" because of the small number of subjects, so these are untested descriptive means.

"Finally, the three control group speakers who finished the posttest seemed to show no difference in ratings. Their overall comprehensibility ratings at pretest were 4.7 and at posttest 4.87, while fluency ratings were 5.23 at pretest and 5.53 at posttest"
