Overall System Usability Scale score. The SUS score is located on a scale ranging from 0 to 100. Adjective ratings provide interpretation of the SUS score. The acceptability range indicates whether the evaluated interface of the system is acceptable or not. Quartile ranges illustrate the average SUS score of all SUS studies (average SUS score of all SUS studies lies around 68), meaning that values around the 2nd quartile represent an average result, based on all SUS studies
