What potential issues can arise from having outliers in a dataset?
- Outliers can increase the value of the mean
- Outliers can lead to incorrect assumptions about the data
- Outliers can make data analysis easier
- Outliers can make the data more diverse
Outliers, which are extreme values that deviate significantly from other observations in the data, can cause serious problems in statistical analyses. They can affect the mean value of the data and distort the overall distribution, leading to erroneous conclusions or predictions. In addition, they can affect the assumptions of the statistical methods and reduce the performance of statistical models. Hence, it's essential to handle outliers appropriately before data analysis.
