What is the statistical significance of outliers in data analysis?
Outliers can significantly affect the results of statistical analyses, potentially skewing the data.
How do outliers influence measures like mean and standard deviation?
Outliers can inflate the mean and standard deviation, making the data appear more variable than it actually is.
Are there methods to detect outliers?
Yes, common methods include the Z-score method, IQR method, and visualizations like box plots.
Should I remove outliers from my dataset?
It depends on the context. If they are errors, removing them may be justified; if they are valid observations, they should be retained.
