Scientific Method and Variables

What is the role of the Dependent Variable in an experiment?

• It is the outcome that is measured to see if it changes in response to the independent variable.

• It is the variable that is manipulated by the researcher.

• It is a constant that does not change throughout the experiment.

• It is the variable that is kept the same in all trials.

What is an Independent Variable?

• The variable that is changed or manipulated in an experiment to test its effects on the dependent variable.

• The variable that remains constant throughout the experiment.

• The variable that is measured in response to changes in the independent variable.

• The variable that is not affected by any other variables in the experiment.

How do you identify the Independent Variable in an experiment?

• It is the one factor that is changed by the experimenter, while all other conditions are kept the same.

• It is the variable that is measured in the experiment.

• It is the variable that remains constant throughout the experiment.

• It is the factor that is influenced by the independent variable.

What is a Suggested Solution?

• A definitive answer to a problem.

• A testable prediction about the relationship between two or more variables.

• An unverified assumption about a variable.

• A random guess without any basis.

What is a Scientific Experiment?

• A casual observation made in nature.

• A structured procedure carried out to test a hypothesis, involving controlled conditions and variables.

• An unplanned event that leads to a discovery.

• A theoretical discussion about scientific principles.

What is the difference between qualitative and quantitative data?

• Qualitative data involves numerical measurements, while quantitative data describes characteristics or qualities.

• Qualitative data describes characteristics or qualities, while quantitative data involves numerical measurements.

• Qualitative data is always more reliable than quantitative data.

• Quantitative data is subjective, while qualitative data is objective.

What is a Conclusion in the Scientific Method?

• A detailed explanation of the experimental procedure.

• A summary of the results of an experiment, discussing whether the hypothesis was supported or refuted.

• A list of all the materials used in the experiment.

• An introduction to the research question being studied.

What are Control Variables?

• Variables that are manipulated to observe their effect on the dependent variable.

• Variables that are kept constant throughout an experiment to ensure that the results are due to the independent variable.

• Variables that are measured to determine the outcome of an experiment.

• Variables that are randomly assigned to different groups in an experiment.

What is the purpose of a Control Group?

• To provide a baseline for comparison against the experimental group, helping to isolate the effects of the independent variable.

• To ensure that all variables are kept constant throughout the experiment.

• To manipulate the independent variable without any restrictions.

• To increase the sample size for more reliable results.

What is a Research Question?

• A hypothesis that needs to be tested.

• A clear, focused question that guides the direction of an experiment or study.

• A summary of the research findings.

• A statement of the research objectives.
