Can power posing (think Superwoman) make you more powerful? According to Carney, Cuffy & Yam (2010) "That a person can, by assuming two simple 1-min poses, embody power and instantly become more powerful has real-world, actionable implications". Zabetipour, Pishghadam and Ghonsooly (2015) wondered whether this could help learners of English as a foreign language (EFL), in particular whether "whether open or closed postures affect EFL learners' moods". During a number of different sessions participants were asked to sit in their usual posture ("Ordinary"), in an open expansive posture ("High power") or in a closed contracted posture ("Low power"). The researchers used the Global Mood Scale (GMS) to assess their participants' feelings after each session (a high score indicates a good mood). Simulated data based on the reported means and standard deviations for a sample of 15 students after different sessions each adopting one of the postures is provided in the data file GMSdata.csv (download by clicking the link). Conduct an appropriate parametric test on the data by hand and SPSS. Use the Tukey HSD procedure for any necessary follow-up tests by hand. You will need to write a summary of the results in APA format for the next part of the assignment as well as answering the following questions... Quote all numerical answers to two decimal places (2 d.p.) except probabilities which should be quoted to three decimal places (3 d.p.). All parts are equally weighted (i.e. 1 mark each) . What is . What is N S N What would the CD for Tukey's HSD be? (use q = 3.499) What is lower limit of the Tukey Confidence interval for the absolute difference in GMS between high and low power postures? What is upper limit of the Tukey Confidence interval for the absolute difference in GMS between high and low power postures? What is Cohen's d for the difference between ordinary posture and low power postures? Use SDordinary as the denominator What proportion of variance in the dependent variable does the independent variable explain (excluding individual differences)?
