A researcher investigated whether factual recall of lecture material presented on colored slides was different from factual recall of material presented on monochrome (black-and-white) slides. The researcher used an independent groups design.
In Condition A, participants watched a 10-minute presentation consisting of 15 facts displayed on monochrome slides. They were then given a test to measure how many facts they could correctly recall.
In Condition B, participants watched the identical 10-minute presentation, but the 15 facts were displayed on colored slides. They were then given the same test to measure how many facts they could correctly recall.
State a non-directional hypothesis for this experiment.
