Final answer:
Using the statistical definition of abnormality, Michael Jordan's basketball skills are considered abnormal because they significantly deviate from the average skill level, though this 'abnormality' is not negative.
Step-by-step explanation:
The question pertains to a psychological concept known as a statistical definition of abnormality. Based on this concept, abnormality can be defined as a significant deviation from the average, in terms of frequency or intensity of a particular behavior or characteristic. Since Michael Jordan's skill level in basketball is extremely high and not common among the general population, using this definition, his abilities could be considered abnormal. However, it's important to note that in this context, 'abnormal' does not carry a negative connotation but simply refers to a statistical rarity in terms of skill level.
