How do I handle outliers in my data analysis?

Handling outliers is crucial as they can skew your results. You can identify them using statistical methods like Z-scores or IQR.

What are Z-scores and how do I use them?

Z-scores measure how many standard deviations an element is from the mean. A Z-score above 3 or below -3 is often considered an outlier.

Are there any methods to remove outliers?

Yes, you can remove outliers based on Z-scores, IQR, or use robust statistical methods that minimize their impact.

What if I want to keep the outliers for analysis?

If you want to keep them, consider using techniques like transformation or robust regression that can accommodate outliers.
