   How to detect outliers in Python?

   • For outlier detection, Python offers a variety of easy-to-use methods and packages. Before selecting a method, however, you need to first consider modality. This is the number of peaks contained in a distribution. For example, imagine that you have a data column composed of athletes’ weights.

   What methods are used in outlier detection?

   • The techniques discussed in this article, such as Z-score and Interquartile Range (IQR), are some of the most popular methods used in outlier detection. The technique to be used depends on the specific characteristics of the data, such as the distribution and number of variables, as well as the required outcome.

   How do you detect outliers?

   • One common way of performing outlier detection is to assume that the regular data come from a known distribution (e.g. data are Gaussian distributed). From this assumption, we generally try to define the “shape” of the data, and can define outlying observations as observations which stand far enough from the fit shape.
