Conclusion
How it Works
An outlier is a data point that significantly differs from the rest of the dataset. This can be due to a variety of factors, such as measurement errors, sampling bias, or truly exceptional cases. Outliers can be either high values or low values, but they must be substantially different from the majority of the data points. To understand outliers, let's consider a simple example:
When to Identify Outliers?
As we've seen, understanding the outlier definition is no longer an optional skill, but a necessary one in today's data-driven world.
