1.Hypnosis has long been thought as an effective alternative to remedy problems such as fear of flying. Some researchers claim that hypnosis can even reduce the level of pain one experiences. In order to verify their claim, a study was conducted to investigate the effectiveness of hypnotism in reducing pain. Nineteen individuals were selected at random and had their level of pain measured before and after hypnosis, where the measurement is in centimetres on a pain scale.^b The difference (Before - After) for each individual in the study was calculated. Tables 3 and 4 show the Shapiro-Wilk test (test of normality) and the descriptive statistics for the differences, respectively.
