How it Works
- Outliers are always extreme values: outliers can also be values that are significantly higher or lower than expected
- Z-score: measures the number of standard deviations from the mean
- Improved predictions: by accounting for anomalies and unusual events
- Enhanced decision-making: by providing a more accurate understanding of the data
- Unusual events or circumstances
- Univariate outliers: These are data points that fall outside the normal range of a single variable.
- Sampling errors
- Business leaders: who make data-driven decisions
- Density-based spatial clustering of applications with noise (DBSCAN): a clustering algorithm that identifies outliers based on density and proximity
- Data scientists: who work with complex datasets and machine learning algorithms
- Outliers are always errors: while errors can contribute to outliers, they are not always the case
- Online courses: on platforms like Coursera, edX, and Udemy
- Over-identification: incorrect identification of outliers can lead to over-interpreting the data
- Data entry mistakes
- Interquartile range (IQR): measures the difference between the 75th and 25th percentiles
- Multivariate outliers: These are data points that fall outside the normal range of multiple variables.
- Increased efficiency: by reducing errors and improving data quality
- Analysts: in industries like finance, marketing, and operations
- Under-identification: failure to identify outliers can lead to missed opportunities and inaccurate predictions
