The referenced graphs measure performance and perceived ability on 4 different tasks. You're right that ideally you'd pool this data to get to an overall correlation, but for the point the author makes, eyeballing it and taking a mental average does the trick, no? Also, what corner of the universe are you from? Loess regression, hierarchical modeling, conditional analyses... methods for finding "non-global" correlations aplenty. |
