What is data in scientific experiments?

• A. Data are final results after experimentation.
• B. Data are numbers and observations collected before, during, and after an experiment.
• C. Data are opinions used to justify conclusions.
• D. Data are theoretical models not verified by experiments.

Answer: (B)

Data are the empirical evidence collected in an experiment—measurements, counts, and observations that come from planning, carrying out, and reviewing the study. They can be numerical values like temperatures, masses, or pH, or descriptive notes about what was seen or felt during the procedure. This information provides the factual basis for analyzing results and deciding whether the hypothesis is supported. Data are gathered before, during, and after an experiment to capture all relevant information and to allow reliable conclusions. That’s why the best description is the one that includes both numbers and observations across the different stages of the experiment. Data are not final results by themselves, nor are they opinions used to justify conclusions. They are not theoretical models; those are ideas or predictions that experiments can test.
