Under which circumstances would it be appropriate to remove outlying data points from the analysis and conclusion in a scientific study?

If an outlying data point causes the analysis and conclusion of a scientific study to become error then it would be appropriate to remove the underlying data points from the analysis and conclusion in a scientific study.

Explanation:

In some cases, the underlying data might be error due to the mistakes in extracting the data and its procedures. Also, in some cases the underlying data might cause scientific data to be full of error.

This will cause the scientific analysis to go in vain. In such cases the underlying data points from and analysis and conclusion of a scientific analysis and conclusion can be removed.
