Hello Likith,
Great question! Yes, there are several ways to remove or handle outliers in Excel beyond just filtering manually:
1. Z-Score method:
Compute the mean and standard deviation of your dataset. Then calculate Z-scores using (value – mean)/standard deviation. Data points with Z-scores above 3 or below –3 are often treated as outliers.
2. Conditional Formatting:
You can highlight outliers visually by applying rules based on either the IQR or Z-score thresholds. This helps identify them quickly before deciding whether to remove them.
The best method depends on your dataset and the type of analysis you’re performing. Sometimes outliers should be removed, while other times it’s better to keep them but analyze separately.
Hope this helps!
Kind regards,
