A group of women suffering from various types of fears is given a therapeutic course to learn how to handle their fear. Before the beginning of the course they were asked to answer a questionnaire to measure their fear score. At the end of the course the women answer the questionnaire again as a follow up measure. The fear scores are used to produce the following: Pair 1(before - follow up) Mean Standard deviation t df 2.520 4.417 2.853 24 i.
