What type of data is organized in a specific format, such as rows and columns?

1. Unstructured data

2. Nominal data

3. Structured data

4. Ordinal data

The correct answer is: Structured data

Structured data refers to information that is organized in a predefined manner, such as rows and columns, enabling easy access and analysis. This type of data is typically stored in relational databases or spreadsheets, where each row represents a record and each column signifies a specific attribute of that record. The organization of structured data allows for straightforward querying and data manipulation using languages like SQL. In contrast, unstructured data lacks a specific format, making it more challenging to collect, process, and analyze. Nominal and ordinal data are categories of qualitative data that describe attributes without a fixed structure. Nominal data represents distinct categories without order, while ordinal data involves ordered categories. However, neither is organized in the rows and columns format characteristic of structured data.
