A program to test equality of two or more coefficients of variation

Two tests of the hypothesis that two or more samples are drawn from populations with equal coefficients of variation are reviewed, and their use is illustrated A program that performs the tests, written in QuickBASIC, is described.     

Effects of stimulus characteristics and sex of subject on perceived emotion

To determine the influence of pupil size, eye size, sex of stimulus face, and sex of subject on perceived emotion, 308 college students filled in missing features on stimulus faces. Each face was independently rated by two male judges on a continuum of negative to positive emotion. Analysis indicated that sex of subject was the only variable to affect perceived emotion. Women (n = 175) tended to draw faces that were judged to be more positive than faces drawn by men (n = 133).
