Study Notes
Purpose of a Hypothesis
- A hypothesis serves as a testable prediction about the relationship between variables in an experiment.
- It guides the research by providing a focused question to be explored.
Independent Variable
- An independent variable is the factor that is manipulated or changed by the researcher to observe its effect on the dependent variable.
- It is the presumed cause in a cause-and-effect relationship in an experimental study.
Control Group
- A control group is a baseline group in an experiment that does not receive the experimental treatment or intervention.
- It is used for comparison against the experimental group to determine the effect of the independent variable.
Replication of Results
- Results are replicated in scientific research to ensure reliability and validity of findings.
- Reproducibility helps confirm that results are consistent and not due to chance or experimental error.
Characteristics of a Well-Designed Experiment
- A well-designed experiment includes a clear and testable hypothesis, controlled conditions, and proper identification of variables.
- It ensures that data collection methods are reliable and that the experiment can be repeated to verify results.
