Huynh-Feldt correction. When ε≤ 0.75 (or you don’t know what the value for the statistic is), use the Greenhouse-Geisser correction. When ε > .75, use theHuynh-Feldt correction. Back to Top Related Articles Grand mean ANOVA vs Regression ...
A Greenhouse–Geisser correction was applied whenever necessary. Due to the non-normal distributions of most variables, as indicated by Komolgorov–Smirnov tests, additional non-parametric tests were applied to confirm significant effects obtained with parametric statistis.

The performance differences were analyzed with a between-subjects repeated measures ANOVA. The assumption of sphericity was violated, therefore degrees of freedom were corrected using Greenhouse-Geisser correction. The performance significantly differed between the three conditions (\(F(1.6,34.8) =73.0, p...
ANOVAs on data in (C) and (D): Greenhouse-Geisser correction with repeated-measures, Tukey-Kramer HSD tests. ∗p < 0.0001 relative to stable1; ∗∗p < 0.0001 relative to rotating room frame. Box plots indicate minima, maxima, median, upper quartile, and lower quartiles. Download: ...
However, there was a significant main effect of outcome, F(1.286, 159.458) = 455.039, p < .001 (η 2 = .786), while the button by outcome interaction fell just short of significance following a Greenhouse Geisser correction F(2.058, 255.186) = 2.82, p = .06. The main effect of ...
Greenhouse–Geisser correction is applied when necessary. Nonsignificant, theoretically interesting findings are reported along with observed power estimates. Results An initial analysis of the behavioural and EEG data was used to determine whether participants should be excluded from the data set. Three ...
In cases of sphericity violations, Greenhouse–Geisser-corrected values are reported. Post hoc analyses used Bonferroni-corrected p-values for multiple comparisons. Immersion questionnaire data. Data from the immersion questionnaire were extracted as one total immersion score (average value over all ...
For ANOVA, Greenhouse-Geisser adjustment was interpreted when Sphericity was violated, and relevant significant main effects and interactions were explored via Bonferroni adjusted pairwise comparisons. For ANOVA, Partial eta squared (η2) was reported with as a measures of effect size [66] and was ...
For the ANOVA on appetitive behavior, Mauchley’s Test of Sphericity indicated that the sphericity assumption was violated (χ2 (2) = 59.12, p = 0.001) and, thus, a Greenhouse–Geisser correction was used. There was a significant main effect of product (Greenhouse–Geisser corrected, F (5.9...
The Greenhouse–Geisser correction was performed in case of violation of sphericity. Significance levels were set atp< 0.05. Post hoct-test comparisons were controlled via the Holm–Bonferroni method. All post hoct-testpvalues are reported as Holm–Bonferroni-corrected values. All statistical tests ...
