Question

When analyzing a scatterplot with a cluster, why should outliers generally be excluded when interpreting the relationship of the variables?

Answer 1

Explanation:

Outliers are often extreme values that are not as a representative of the data set as the other points in the cluster.

If the outliers are included, a description of the data set might be misrepresented.

Therefore outliers generally are excluded when interpreting the relationship of the variables.
