Which term indicates that something is not typical?

The term that indicates something is not typical is "uncharacteristic." This word is used to describe a situation, behavior, or feature that deviates from what is usual or expected. When something is labeled as uncharacteristic, it suggests that it does not align with the established norms or traits associated with a person, object, or situation. For example, if someone known for being punctual arrives late, that behavior can be termed uncharacteristic of them.

The other terms have distinct meanings that relate more to typical behavior or attributes. "Characteristic" refers to a feature or quality that is typical of a person or thing, "uniform" suggests consistency or sameness, and "standard" denotes a level of quality or attainment that is considered normal or acceptable. In contrast, "uncharacteristic" directly conveys the idea of divergence from the norm, making it the appropriate choice in this context.
