You notice that using the Z-score method for a particular data set is yielding too many outliers. What modifications can you make to the method to reduce the number of outliers detected?
- Decrease the Z-score threshold
- Increase the Z-score threshold
- Use the IQR method instead
- Use the modified Z-score method instead
Increasing the Z-score threshold will mean fewer points will exceed it, thus fewer outliers will be identified.
