Why might researchers consider the presence of outliers in their data?

Researchers often consider the presence of outliers in their data because these unusual values can provide valuable insights into the subject being studied. Outliers may indicate variability in the data, reveal trends or patterns that were not previously anticipated, or highlight significant phenomena that warrant further investigation. For example, an outlier may represent a rare but important case that can enhance understanding of the research question.

In various fields, outliers can be pivotal in identifying exceptions to standard behaviors or can drive new hypotheses. By examining these data points closely, researchers can discover significant information that could impact conclusions about the overall dataset.

While it's essential to analyze outliers carefully, they should not be dismissed outright, as they may contain critical knowledge about underlying processes or factors affecting the research topic. This contrasts with other considerations regarding outliers, where certain perspectives emphasize minimizing their influence on results rather than exploring their potential contributions to understanding the data.
