outlier 🔊
Meaning of outlier
An outlier is a data point, observation, or individual that differs significantly from others in a group, often due to being unusually high or low.

Unlike similar terms like 'exception' or 'anomaly,' an outlier is specifically used in statistical or observational contexts to denote something that deviates from the norm.

- The scientist discovered an anomaly in the experiment's results.
exception 🔊
Meaning of exception
