Answer 1

Outliers in the data need to be cleaned. Whether an outlier should be removed depends on the nature of the data and the purpose of the analysis.

Step-by-step explanation:

Outliers in the data need to be cleaned. Outliers are data points that are significantly different from the other data points and may be errors or abnormality. Whether or not an outlier should be removed depends on the nature of the data and the purpose of the analysis. Sometimes they should be removed if they are likely to be incorrect data, and other times they should be kept if they provide valuable information about the population under study.
