Model 3 contrast analysis stratified by knowledge type and number of correct questions. Contrasts for viewers versus identical non-viewers were "0.201 (.007)" for technical and "0.246 (.026)" for contextual knowledge.

"Watching the multimedia presentation raised the probability of correctly answering these test questions by about 20 points (from about 65/100 to about 84/100)—a large effect."
