Which of the following best defines something that deviates from the general or common order or type?

The term that best defines something that deviates from the general or common order or type is "anomalous." This word specifically describes something that is unusual, abnormal, or inconsistent with what is standard or expected. An "anomaly" in a scientific or statistical context refers to data or events that do not fit into the established pattern or framework, indicating a deviation from the norm.

In contrast, the other options describe states that align with generality or commonality. "Normal" refers to what is standard or typical, while "conventional" denotes adherence to established practices or norms. "Regular" implies something that is consistent or occurs at defined intervals. Thus, "anomalous" stands out as the word that encapsulates the idea of deviation from the norm, making it the appropriate choice for this question.
