2.6. Statistical Analysis
EVENT
Prior to analysis, all data were assessed to ensure normal distribution, homogeneity of variance and sphericity. If sphericity was violated, a Greenhouse–Geisser correction was applied. Statistical evaluation of cognitive and performance changes was accomplished using repeated analysis of variance (ANOVA). In the event of a significant F ratio, least significant difference (LSD) post-hoc pairwise comparisons were used to examine the differences. The POMS, GDS and GAS were evaluated on an ordinal scale; thus, the Friedman non-parametric test was used to analyze group differences. All statistical analyses were analyzed using SPSS v27 software (SPSS Inc., Chicago, IL, USA), and an alpha level of
