- Learn how to design experiments to prove causation using precise, measurable definitions.
- Identify the manipulated variable (independent) and the measured outcome (dependent) in an experiment.
- Understand how researcher and participant expectations can skew results and how blinding mitigates this.
- Recognize how human expectation can trigger genuine biological responses, requiring placebo controls.
- Differentiate between selecting a representative participant pool and distributing participants evenly into groups.
- Understand the real-world constraints on experimental design, including ethical boundaries and sample bias.
- Learn about the process of scientific scrutiny and the challenge of replicating past research findings.
- Distinguish between consistency (reliability) and accuracy (validity) in measurement tools.
- Use scientific principles to evaluate personal beliefs and information in the digital age.
