ChemistryChapter 16: Empirical Data Collection and Analysis
Experiments
A fair experiment gives high control: you change one factor and watch the rest.
Learning objectives
- Define and explain experiments.
- Apply experiments to a focused FBISE question.
- Check the answer for correct terms, evidence, working, and units.
Definition
A fair experiment gives high control: you change one factor and watch the rest. The cost is time, money, and errors. You still run it because talk is not evidence. Plan, measure, and write the raw table before you average.
