Study Notes
Factors Affecting Experimental Outcome
- Experimental conditions significantly influence results.
- Sample size impacts statistical significance.
- Control groups provide a baseline for comparison.
- Randomization minimizes bias.
- Independent and dependent variables dictate the outcome.
Hypothesis in Scientific Research
- A hypothesis is a testable prediction.
- It guides the research design and data analysis.
- It provides a framework for explaining observations.
Ensuring Reliable Data
- Replication helps verify the accuracy of results.
- Control groups minimize extraneous variables.
- Standardized procedures ensure consistency.
- Blind or double-blind studies reduce experimenter bias.
Reasons for Repeating Experiments
- Confirm original findings and increase confidence.
- Explore alternative explanations or refine the hypothesis.
- Test the generalizability of the results.
- Identify potential errors in the original study.
Confounding Variable
- A confounding variable is a factor that influences both the independent and dependent variables.
- It can obscure the true relationship between variables.
- It can lead to misleading conclusions if not accounted for.
