Glossary for Geospatial Science

outliers: �Geodata points that lie far from the regression line.� Outliers can be legitimate geodata points that show the extreme variability of the geodata or they can represent errors, such as incorrectly recorded geodata, an instrument malfunction, and so forth.� Researchers drop outliers from statistical analyses when the outliers are shown to be errors because the outliers can skew statistical analyses.
