A didactical dataset to learn supervised classification with candy

A didactical dataset to learn supervised classification
It was obtained from university level students measuring candy that was mixed and distributed in bowls to them. The goal of this dataset creation was to expose the students to the data taking process. Further, the dataset is meant for classification.
