Which term refers to the first row in a spreadsheet that labels the type of data in a column?

1. Header

2. Header row

3. Function

4. Leading question

The correct answer is: Header

The term "header" signifies the first row in a spreadsheet that contains labels for the types of data found in each corresponding column. This header row is crucial for organizing data, as it provides context and clarity regarding what each column represents, enabling users to understand the dataset more effectively. Without headers, data could easily become confusing, especially in large datasets where clarity is vital for analysis. While the term "header row" could also describe the same concept, it is typically a more specific phrasing that includes the word "row," whereas "header" alone suffices in many contexts to convey the necessary information about column identifiers. Understanding these terms is fundamental in data organization and analysis, as properly labeled data enhances interpretability and usability in various analytical tasks.
