Determine whether the data described are nominal or ordinal. The flavors of shaved ice treats are grape, cherry, orange, watermelon, and coconut
The correct answer and explanation is:
Correct Answer: Nominal
Explanation:
The data described — the flavors of shaved ice treats: grape, cherry, orange, watermelon, and coconut — are nominal data.
Nominal data is a type of categorical data used to label or name variables without implying any order or ranking between them. In nominal data, the categories are mutually exclusive and unordered — one category is not more or less than another, just different.
In this case, the shaved ice flavors (grape, cherry, orange, watermelon, coconut) are simply names of different types of flavors. There is no natural order to these flavors. For example, “grape” is not higher, lower, better, or worse than “cherry” or “coconut” in any inherent way — it’s just a different flavor. That makes them nominal categories.
Why Not Ordinal?
Ordinal data refers to categories that do have a meaningful order or ranking, but the differences between the ranks are not measurable. For example, if the data were something like small, medium, large, or first, second, third, those would be ordinal, because there’s a clear ranking.
However, with shaved ice flavors, there is no built-in order or ranking. Someone might prefer grape over cherry, but that is based on personal preference, not a structured or standard hierarchy. There’s no consistent rule that says one flavor comes before or after another.
Summary:
- Type of data: Categorical
- Are the categories named? Yes
- Do the categories have a logical order? No
- Therefore, the data type is: Nominal
This classification is important in statistics because it influences which kinds of analysis and graphs are appropriate. For nominal data, you would typically use bar graphs or pie charts and analyze using counts or percentages, not means or medians.
