Unstandardized (Beta) and standardized coefficients (β) of the linear model: predicting jumping synchrony from experimental group (together vs. separate), initial rapport, and mood. Beta, 95% confidence intervals (CI), and β have been back-transformed to the original scale of the dependent variable (bounded between −1 and 1). Standard errors (<i>SE</i>), <i><i>t</i></i>-values, <i><i>p</i></i>-values, and Cohen’s <i><i>f²</i></i> remain on the Fisher-transformed scale.
