q2 i? Analysis of covariance, with pre-test scores as covariate, confirmed that the experimental group's adjusted post-test speaking-skill score was significantly higher than the control group's. → Jose 2012

ANCOVA was applied to the final speaking-skill score with pre-test scores partialed out as a covariate. The adjusted mean for the experimental group was 67.36 compared to 27.25 for the control group, a statistically significant difference at the 0.01 level.

"The value of the ANCOVA (Fy. x =621.310) is significant at 0.01 level. From Fy.x, it is clear that the final average score on speaking skill, after adjusted for the initial difference in experimental group (67.36) differ significantly from that in the control group (27.25)."
