This tutorial demonstrates how to analyze consumer acceptability data obtained using hedonic scales, focusing on the appropriate use of ANOVA under different experimental designs. It covers the application of a Randomized Complete Block Design (RCBD) and Repeated Measures ANOVA using R, including post-hoc testing with the agricolae package and data visualization with ggplot2. The examples are based on simulated sensory data and are intended for students, researchers, and professionals in food science and sensory analysis.
