What is outlier removal in data analysis?
Outlier removal is the process of identifying and eliminating data points that differ significantly from other observations.
Why is it important to remove outliers?
Removing outliers is crucial as they can skew results, affect statistical analyses, and lead to misleading conclusions.
How do I identify outliers in my dataset?
You can identify outliers using methods like the Z-score, IQR (Interquartile Range), or visualizations like box plots.
Can you give me an example of outlier removal?
Sure! If you have a dataset of people's ages and one entry is 150, that would be an outlier and could be removed.
