Outlier Calculator
Identify statistical outliers in your dataset using either the IQR (Interquartile Range) or Standard Deviation method.
Understanding Outliers
Outliers are data points that differ significantly from other observations in a dataset. They can be identified using two main methods:
IQR Method
Uses the Interquartile Range (IQR) to identify outliers:
- Lower bound = Q1 - 1.5 × IQR
- Upper bound = Q3 + 1.5 × IQR
Standard Deviation Method
Uses the mean and standard deviation:
- Lower bound = Mean - 2 × Standard Deviation
- Upper bound = Mean + 2 × Standard Deviation
