CompTIA Data+ (DA0-002)Data Concepts and EnvironmentsEasy
A data analyst is working with a dataset containing customer feedback. Each entry includes a unique ID, the date of feedback submission, and a free-text comment describing the customer's experience. Which of the following best describes the data type of the 'free-text comment' field?
- ABoolean
- BCategorical
- CNumerical
- DText
Show answer & explanationAnswer & explanation
Correct answer: D. Text
The 'free-text comment' field contains unstructured human language, which is best classified as a text data type. This allows for storage of arbitrary strings of characters.
Why the other options are wrong
- A. Boolean data represents true/false values, which is not applicable to customer comments.
- B. Categorical data represents discrete groups or labels, not free-form text.
- C. Numerical data consists of quantifiable values, which comments are not.
Text Data Type
A data type used to store sequences of characters, often representing human language or descriptive information.
- Can include letters, numbers, symbols, and spaces.
- Often used for names, addresses, descriptions, and comments.
- Typically requires more storage than numerical or boolean types.
Memory trick: Think of data types as different drawers in a filing cabinet, each holding a specific kind of information.
