This exercise uses data from Effectiveness and economic evaluation of a nurse delivered home exercise programme to prevent falls. 1: Randomised controlled trial (Robertson et al. (2001) British Medical Journal 322, 697-701.) We looked at this paper in Week 5. Question 4 of that exercise was:
"There were 9 serious falls in the control group and 2 in the exercise group, P=0.033. What is meant by 'P=0.033'? What does it tell us about the effect of exercise on falls?."
In the paper the method used to find this P value was Fisher's exact test. The data are on file falldata.sav.
Question: Using SPSS, cross-tabulate experiences of falls by treatment group and carry out Fisher's exact test.
