You should detect outliners and visualize them in this issue, namely:
Detect outliners using techniques such as: Isolation Forest, Local Outlier Factor (LOF), or Elliptic Envelope.
Visualize outliners with plots (for example scatterplots with outliners marked) Note that you may need to do Dimensionality Reduction if the points or outliners have high dimensionality.
Analyze the outliners and conclude whether they are noise or if they contain important information, then explain whether you will keep them in the analysis and why.
