You find that both Z-score and modified Z-score methods give different sets of outliers for the same dataset. How will you reconcile this?
- Assume the Z-score method is correct
- Assume the modified Z-score method is correct
- Consider the intersection of both methods
- Further inspect the data and the assumptions of each method
When two methods give different sets of outliers, it's best to further inspect the data and the assumptions of each method before drawing conclusions.
