Text data analysis is defined as which of the following?

• A. Summarizing numerical datasets
• B. Extracting and classifying data from textual sources
• C. Translating text into code
• D. Creating visual dashboards

Answer: (B)

Text data analysis means turning written content into structured insights. It involves extracting information from text sources and then categorizing or classifying that information so it can be used for decision making. The choice that describes both pulling out relevant data from language and organizing it into categories is the best fit. For example, extracting entities, topics, or sentiments from customer reviews and then labeling them for analysis.

Other options miss the essence: summarizing numerical datasets focuses on numbers rather than text; translating text into code is about converting language into programming instructions rather than analyzing content; creating visual dashboards is about presenting results, not performing the analysis itself.
