Document Summary
Ask people to take 10 deep breaths using diaphragmatic breathing 3 times a day. i: measure their heart rate at 4 different time points (i. e. baseline, 2 weeks, 4 weeks, and 6 weeks). c) H03: all . jk are equal: alternative hypothesis: i. ii. iii. H13: not all the . jk are equal: assumptions: Independence of residuals. a: homogeneity of variance for residuals, normality of residuals. H03: all . jk are equal: alternative: i. ii. iii. H13: not all the . jk are equal: descriptives, check sphericity assumption, failed, we have to use either gg or hf. Is there an interaction: both gg and hf work (p > 0. 05), so we use gg. Is there a main-effect for the between subject variable: follow-up contrasts, apa results write-up, mauchly"s test indicated that the assumption of sphericity had been violated (x2 = Lesson 13: mixed design anova: these findings provide support that practicing diaphragmatic breathing decreases heart rate over time.
