2.7. Statistical Analysis
Data were analysed on IBM SPSS Statistics (version 26; IBM, Portsmouth, UK). Descriptive statistics were used to summarise demographic characteristics and outcome data. For continuous outcomes, mean and standard deviation were calculated.Summary data for PSD were presented as mean % weight (mechanical sieving) or mean % volume (laser diffraction) and standard deviation (SD). To assess inter-individual variation at each level of particle size, a coefficient of variation (CV) was calculated for each sieve aperture size within each almond type using the formula: CV (%) = (SD/mean) × 100.Before analysis, all continuous raw data were checked for normality and outliers using Q-Q plots and the Shapiro–Wilk test. Student’s paired
