Chapter 16.2
Research Methods & Data Collection: The Science of Gathering Evidence
Explore the principles of scientific research, from forming a hypothesis and designing controlled experiments to collecting reliable data and upholding research ethics.
What You'll Learn
Controlled experiments require independent, dependent, and controlled variables identified.
Reliability measures consistency while validity measures true measurement accuracy.
Quantitative data uses numbers while qualitative data describes observable characteristics.
Ethical research demands informed consent and honest transparent data reporting practices.
What You'll Practice
1
Students distinguish reliability from validity using real thermometer measurement scenarios.
2
Learners evaluate sampling bias and identify appropriate experimental variable types.
3
Practice questions test data quality terms, graph types, and scientific integrity.
Why This Matters
Mastering research methods and data collection equips students with the evidence-based thinking skills essential for scientific careers and informed decision-making in everyday life.
