Answer: (D)

Verified step by step guidance

1. Understand the definition of nominal data: Nominal data represents categories or names without any intrinsic order or ranking. These categories are simply labels used to distinguish different groups.
2. Review each option to determine if it fits the nominal data definition:
3. Scores on a math test are numerical and represent quantities, so they are not nominal; they are typically considered interval or ratio data.
4. Heights of students measured in centimeters are numerical measurements with meaningful order and differences, so they are ratio data, not nominal.
5. Temperature measured in degrees Celsius is numerical and has meaningful order and intervals, so it is interval data, not nominal.
6. Types of fruits such as apple, banana, and orange are categories without any inherent order, making them a perfect example of nominal data.
