Final answer:
The statement "the candy is sour" is a qualitative observation describing the quality of the candy's taste, not an inference or prediction.
Step-by-step explanation:
The statement "the candy is sour" is an example of a qualitative observation. Qualitative observations describe properties or occurrences that do not rely on numbers but rather on qualities. In this case, the taste sensation of sourness is a quality of the candy.
It is neither a type of inference (deductive, inductive, nor abductive) nor a quantitative observation, which would require numeric measurement. Nor is it a prediction or an inference per se; it's a statement that likely comes from direct sensory experience.
