**2.15. Statistical analysis**

Statistical significance was set at *p* < 0.05. One-way ANOVA with Bonferroni post-hoc test was conducted on all the parameters studied to compare between the seasons. These were performed with GraphPad Prism ver.5.0 for Windows (San Diego, CA, USA). The parameters were then analysed with multivariate analysis of all the honey samples. The correlation matrix was calculated, giving the correlation coefficients between each pair of variables present. To identify variability and to reduce the dimensions of the dataset, principal component analysis (PCA) was performed, using the XLSTAT Version 2011.5.01 software (Addinsoft, New York, NY, USA).
