Group 3’s values range from a minimum of 0 to a maximum of 34. Group 2’s values range from a minimum of 11 to a maximum of 37. Group 1’s values range from a minimum of 6 to a maximum of 49. In the second part, all the analyses in the compare mean section of SPSS are discussed like One way ANOVA or one-way analysis of variance, One-sample t-test.The interval around group 3’s mean ranges from 12.74 to 21.01. The interval around group 2’s mean ranges from 19.99 to 25.76. The interval around group 1’s mean ranges from 23.46 to 30.84. Lower bound gives the lower end point of the 95% Confidence Interval of the mean and upper bound give the upper end point of the 95% Confidence Interval of the mean.For group 1 it is 1.796, for group 2 it is 1.394, and for group 3 it’s 1.998. Error gives the standard error of the mean for each group. Deviation is the standard deviation of anxiety for each group. Group 1 has a mean of 27.15, group 2 has a mean of 22.88 and group 3 has a mean of 16.88. The One-Way ANOVA Options dialog box appears: Click in the check box to the left of Descriptives (to get descriptive statistics), Homogeneity of Variance (to get a test of the assumption of homogeneity of variance) and Means plot (to get a graph of the means of the conditions.): Click on the Continue button to return to the One-Way ANOVA dialog. Mean is the mean anxiety value of each group.We see that group 1 (no treatment) has 27 subjects, group 2 (biofeedback) has 24 subjects, and group 3 (CBT) has 24 subjects. N is the number of subjects in each group.This table gives the descriptive statistics for each treatment group, and for the combination of the three groups.
