q3 · i? · causal · r2

One-way ANOVA on the three groups' listening post-test scores (n=45 total). Post-test means were 45.86 (full), 38.13 (keyword), and 33.86 (no captions); the omnibus test was significant, F (2, 42) = 103.51, p<.01.

"Table 4, clearly indicated that the difference between the means of the three groups was statistically significant. F (2, 42) = 103.51, p<.01."

Scheffé post hoc multiple range test on post-test scores. The full-text group exceeded the keyword group by a mean difference of 7.73333 and the no-text group by 12.00000, both significant at the 0.05 level.

"According to Table5, the full captions group performed better than the keyword captions group and both of them significantly higher than the no-captions group."
