2.7.4. Statistics

Data were analyzed in MATLAB. The Gaussian distribution of the data was assessed using the Anderson–Darling test. If the data sets were normally distributed, the data were tested for significance using a paired *t*-test (two related samples) or one-way repeated measures ANOVA (>2 related samples). If the data sets were non-normally distributed, the data were tested for significance using the Wilcoxon signed-rank test (two related samples), Friedman's test (>2 related samples), or the Kruskal-Wallis test (>2 unrelated samples). Tukey post-hoc tests were used to directly assess group di fferences following ANOVA where appropriate. Where boxplots are used to represent the data, the median is plotted as a line within a box formed by the 25th (q1) and 75th (q3) percentiles. Points are drawn as outliers if they are larger than q3 + w × (q3 − q1) or smaller than q1 − w × (q3 − q1).
