Report the results of the experiment described in question 1 in American Psychological Association format.Include an table of all the pairwise differences with their size, the Tukey HSD 95% CI and Cohen's dfor the difference calculated using the standard deviation for the 'ordinary' posture group as the denominator.

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 14 students after different sessions each adopting one of the postures is provided in the data
