Comparison of Nutritional Data Analysis

Data were fed to the computer and analyzed using IBM SPSS software package version 20.0. (Armonk, NY: IBM Corp). For continuous data, they were tested for normality by the Shapiro–Wilk test. Quantitative data were expressed as a range (minimum and maximum), mean, and standard deviation for normally distributed quantitative variables Paired t-test was used to compare nutritional facts per serving and laboratory nutritional facts per serving. On the other hand, for not normally distributed quantitative variables, Wilcoxon signed ranks test was used to compare nutritional facts per serving and laboratory nutritional facts per serving. The significance of the obtained results was judged at the 5% level^{24 ,25 (link)}.
