*2.4. Data Analysis*

Due to the small sample size of participants used in both the beef (*n* = 30) and chocolate (*n* = 30) trial, and because the data collected was ordinal, non-parametric tests were used to analyse the data. For the chocolate trial, the Friedman's ANOVA test was performed to determine the effect of the different environmental conditions on participants' hedonic ratings of chocolate samples. Where Friedman's indicated significant differences were present, a Wilcoxon pairwise comparison (with Bonferroni adjustment) was conducted to identify where the differences occurred. In terms of the beef trial, a Wilcoxon signed-rank test was conducted to test if the surrounding environment influenced hedonic ratings of beef samples. The probability level used for significance between responses was set at *p* < 0.05 and all data were analysed using SPSS 25 statistical software (IBM, Armonk, NY, USA).
