q3 i? The only significant presentation-mode effect was on the delayed posttest, where CBI subjects (M = 7.95) surpassed print subjects (M = 7.00), F(1,186) = 8.61, p < .01. → Ross 1988

Follow-up univariate tests from the 2 x 2 MANOVA on achievement in the randomized experiment. No other presentation-mode effects on achievement were significant.

"The only significant presentation mode effect occurred on the delayed posttest, on which CBI subjects (M = 7.95) surpassed print subjects (M = 7.00), F (1,186) = 8.61, p < .01."
