Abstract
Outlier detection is one field of research in data mining. One of the outlier detection algorithms is the Enhanced Class Outlier Distance Based (ECODB) algorithm. In this paper, the ECODB algorithm is used to identify outliers on national exam results, integrity index and accreditation level of senior high schools in the Yogyakarta province year 2015. An experiment by varying number of outlier and varying number of nearest neighbor were done to identify the value of N and K that result on smallest Class Outlier Factor (COF). The identified N and K were then used to find out schools that are classified as outliers. Further decriptive analysis of the schools were then performed, afterward.
