Verified step by step guidance

1. Understand the scientific method: The scientific method is a systematic approach to investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge. It involves forming a hypothesis, conducting experiments, and analyzing results.
2. Define the independent variable: The independent variable is the one that is manipulated or changed by the researcher in an experiment to test its effects on other variables.
3. Differentiate the dependent variable: The dependent variable is the one being measured or observed in response to changes in the independent variable.
4. Clarify the controlled variable: Controlled variables are factors that are kept constant throughout the experiment to ensure that the results are due to the manipulation of the independent variable alone.
5. Explain the extraneous variable: Extraneous variables are any variables other than the independent variable that could affect the outcome of the experiment. Researchers aim to minimize their influence to maintain the validity of the study.
