ANOVA Technique F(1,22)= 9.619, p=0.005 where F is the statistic for ANOVA, group df (degrees of freedom)=1, error of df=22, F ratio or value= 9.619, and p=0.005 is the significance level. The null hypothesis is "Guided Imagery (GI) with Progressive Muscle Relaxation (PMR) would not reduce pain and mobility difficulties of women with OA." The null hypothesis should be rejected because the statistical value of 9.619 is greater than the p value of 0.005, showing a significant level that the GI with PMR does reduce the pain and mobility difficulties. The reduction in mobility at week 12 was statistically significant because the F value of 9.619 is greater than the probability level of 0.005. Yes, because the statistical value of 9.619 is greater than the probability level of 0.001. F(3,60)=4.13, p=0.04 and <=0.01 is still significant because the F value is still greater than the significance level. Yes, the repeated measures analysis of variance is used to analyze data where the same variables are repeatedly measured over time on a group or groups of subjects. F(2,147)=4.56, p=0.003 shows two groups with a sample size of 147. The study has strengths of groups being mutually exclusive with independent observations. The weaknesses include no normal distribution, which creates variance among and within the groups, and no standard deviations for the variables. The strengths show similarities between the groups, but the weaknesses show variances in the members of each
