Google Data Analytics Professional Certification Practice Test

Which of the following best describes nominal data?

1. Data with a set order

2. Data organized in numbers

3. Data categorized without a scale

4. Data showing sequence

The correct answer is: Data categorized without a scale

Nominal data refers to a type of categorical data that allows for classification without any inherent order or ranking among the categories. This means that while you can sort data into distinct groups based on characteristics, you cannot meaningfully arrange these categories in a sequence or assign numerical values to them that would indicate any progression or hierarchy. Examples of nominal data include categories such as gender, hair color, and types of fruit. The other options imply some form of order or numerical relationship which does not apply to nominal data. For instance, data with a set order suggests an ordinal relationship, where categories can be ranked, while data organized in numbers leans towards numerical or quantitative data types. Lastly, data showing sequence clearly refers to a structured order, further indicating a distinction that is absent in nominal data.
