Gender and Humor. Sense of humor of 200 male and 200 female students was examined in a paper. The researchers studied measures of abstract reasoning, verbal intelligence, humor production ability, and mating success. The students’ humor ability was tested on the basis of the number of captionswritten for funny images. Following are the number of captions given by a few participants.
