Underestimating Correlation from Scatterplots.
Strahan, Robert F.; Hansen, Chris J.
Applied Psychological Measurement, v2 n4 p543-50 Fall 1979
Eighty graduate students and faculty estimated the correlation coefficient for each of 13 computer-printed scatterplots. As predicted, subjects underestimated the degree of actual correlation. With substantial moderation by a method-of-presentation factor, this underestimation was most pronounced in the middle of the correlational range. (Author/MH)
