What is an example of qualitative data in a science classroom?

• A. Qualitative data are descriptive (color, texture); quantitative data are numerical (length, temperature).
• B. Qualitative data are numerical; quantitative data are descriptions.
• C. Qualitative data come from experiments; quantitative data come from surveys.
• D. Qualitative data are measured with rulers; quantitative data with feelings.

Answer: (B)

Qualitative data describe qualities or characteristics using words, not numbers. In science, you’d note things like color, texture, shape, or smell. Quantitative data, on the other hand, are measurements you can put a number on—length, mass, temperature, and so on. So for an example of qualitative data in a science classroom, you’d describe the leaf as green, smooth, and oval. That shows the descriptive, non-numeric nature of qualitative observations. The idea that qualitative data are numerical would mix up the definitions, which is why the descriptive example is the correct understanding here.
