How does qualitative data differ from quantitative data?

• A. Qualitative data is numerical; quantitative data is descriptive
• B. Qualitative data can be observed but not measured; quantitative data can be measured
• C. Qualitative data is used exclusively in surveys
• D. Qualitative data requires less analysis than quantitative data

Answer: (B)

The distinction between qualitative data and quantitative data is fundamental in research and data analysis. The correct choice highlights that qualitative data can be observed, often encompassing characteristics, attributes, and descriptions that provide insights into phenomena but are not numerically measurable. This type of data is commonly gathered through interviews, open-ended survey questions, or observations where researchers look for patterns or themes.

On the other hand, quantitative data is characterized by its ability to be measured and expressed numerically, allowing for statistical analysis. This means it can be subjected to mathematical calculations, which can reveal trends and relationships through numbers, such as averages or percentages.

Understanding this difference allows researchers to select the appropriate methods for data collection and analysis based on their specific objectives or the nature of the information they are investigating.
