A student has conducted 2 memory experiments and she would like to compare performance across the two (at least roughly). The problem is that 1 of them was a 2-alternative forced choice test and the other is 3-alternative forced choice test (both were judgments of relative recency). Chance performance being substantially different between the two, a direct comparison isn't appropriate.
Does anybody have a suggestion to correct for chance? I thought of simply subtracting chance from each subject's score but I didn't know if that is acceptable or if there is a better idea.
