If your test returned a small p-value, you should apply a correction, usually either the:Greehouse-Geisser correction. Huynh-Feldt correction.When ε≤ 0.75 (or you don’t know what the value for the statistic i
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.

We employed RM-ANOVA to assess whether there is any significant difference between the health indicator data of complete and imputed datasets [38]. The variance could be biased due to imputation, potentially violating RM-ANOVA assumptions; therefore, we used the Greenhouse–Geisser correction when r...
Greenhouse–Geisser adjustments were applied, if required. Results Psychometric data analyses of the differences in classification accuracy between the SOA conditions, which showed that the interaction resulted from the difference between SOA 100 and SOA 67 (β = −0.47, p < .05; no other ...
The Greenhouse–Geisser correction was applied where appropriate (fractional degrees of freedom and adjusted p values are reported). We used the variance-partitioning procedure described by Chuah and Maybery (1999) to assess the independent and combined contributions of hunger and food liking to desire...
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: ...
EEG preprocessing included a band-pass filter between 0.2 and 80 Hz with a notch filter at 50 Hz. Artefact correction used independent component analysis (ICA) using the logistic infomax algorithm as implemented in EEGLAB (Delorme & Makeig,2004), with extended parameters (learning rate = .001,...
Greenhouse-Geisser correction was applied when prescribed (only corrected p values are reported). The analysis of the central line showed a main effect of longitude (F [2, 70] = 41.33, p < .001, ηG2 = .06); moreover, there was a significant three-way interaction between speaker, ...
In these analyses the degrees of freedom were corrected with the Greenhouse-Geisser ε if ε < 0.7, and the ε values were averaged from Greenhouse-Geisser and Huynh-Feldt when ε > 0.7 in accordance with Stevens (2002). Differences between individual stimuli were investigated by a ...
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 ...
