A variable that falls outside the parameters of what can be expected is referred to as a(n) _________.

• A. Anomaly
• B. Bias
• C. Outlier
• D. Variance

Answer: (C)

A data point that falls far outside what you'd expect based on the rest of the data is an outlier. This term precisely describes a single observation that is unusually distant from the overall pattern, which can signal an error, a special condition, or a highly influential case. In contrast, bias is a systematic error affecting results, and variance is a measure of how spread out the values are, not a single value. Anomaly is similar in meaning but the standard label for a single extreme observation in data sets is outlier.
