A true experiment is this type of research with completely randomized design (CRD) method, three replications, and three treatments. Data were obtained directly from 5 panelists who answered a questionnaire (sensory test format) about the quality of white sweet potato flour kastengel which was referred to as primary data. Then tabulate the data obtained in tabular form and perform analysis of variance (ANOVA). If the analysis of variance shows Fcount>Ftable, proceed to Duncan's test.
