*2.4. Statistical Analysis of Results*

As the tests were repeated 21 times, a statistical analysis was necessary to determine the dispersion between them is so large that there is no relationship, an ANOVA statistical analysis with a 95% confidence level is performed accompanied by their respective DMS and Tukey contrasts. The starting hypotheses are H0 = Equality between curves, and H1 = Inequality between curves.

Some descriptive statistics are also calculated to help determine the level of dispersion between the results. For this purpose, a visual method is used using box diagrams and a quantitative method through Analysis of the Coefficient of Variation (CV).
