Question:
Are you lucky? Parapsychologists define “lucky” people as individuals who report that seemingly chance events consistently tend to work out in their favor. A team of British psychologists designed a study to examine the LO4 effects of luckiness and competition on performance in a guessing task (The Journal of Parapsychology, Mar.
1997). Each in a sample of 56 college students was classified as lucky, unlucky, or uncertain on the basis of their responses to a Luckiness Questionnaire. In addition, the participants were randomly assigned to either a competitive or a noncompetitive condition. All students were then asked to guess the outcomes of 50 flips of a coin. The response variable measured was percentage of coin flips correctly guessed.
