outliers and influential points
Outliers refer to data points that deviate significantly from the rest of the dataset. These points lie at an unusual distance from the majority of the observations, which can be either higher or lower than expected values. Influential points, on the other hand, are data points that have a considerable effect on the statistical analysis or the overall conclusions of a study. These points can greatly impact the results, leading to a different interpretation or generalization of the data.
