What are data points that are considered anomalies called?

• A. Normal values
• B. Outliers
• C. Median values
• D. Average values

Answer: (B)

The term used for data points that deviate significantly from the other observations in a dataset is known as outliers. Outliers can result from variability in the measured data or may indicate experimental errors. They play a critical role in statistical analysis, as they can skew results and impact the overall interpretation of the data. Identifying outliers is essential for accurate data analysis, which helps ensure that conclusions drawn from the dataset are valid and reflective of the true trends within the population. In contrast, normal values, median values, and average values refer to more typical or central measures of a dataset. Normal values indicate what is expected based on the majority of the data, while median values represent the middle point of the dataset when ordered from least to greatest. Average values, or means, are calculated by summing all data points and dividing by the number of points, which can be disproportionately affected by outliers. Understanding outliers is key for effectively interpreting and analyzing data, particularly in market pricing where accurate assessments are essential for making informed decisions.
