Scientific Method

What is a variable in an experiment?

• A variable is a constant factor that does not change during an experiment.

• A variable is any factor that can be changed or controlled in an experiment.

• A variable is the outcome that is measured in an experiment.

• A variable is a type of equipment used in experiments.

What is the significance of peer review in scientific research?

• Peer review is a process that allows researchers to publish their work without any evaluation.

• Peer review ensures the quality and credibility of research by having experts evaluate the work before publication.

• Peer review is primarily used to increase the number of publications in scientific journals.

• Peer review serves as a marketing tool for researchers to promote their work.

What is a dependent variable?

• A variable that is manipulated in an experiment.

• A variable that remains constant throughout the experiment.

• The factor that is measured in an experiment, which is affected by changes in the independent variable.

• A variable that is not related to the experiment.

What is the importance of repeating experiments?

• It helps to verify results and ensure reliability and accuracy.

• It allows researchers to publish more papers.

• It reduces the time needed for experiments.

• It eliminates the need for peer review.

What are the steps of the scientific method in the correct order?

• 1. Ask a question (Observation), 2. Conduct background research, 3. Formulate a hypothesis, 4. Conduct an experiment, 5. Analyze data, 6. Draw conclusions, 7. Communicate Results

What is the role of observation in the scientific method?

• Observation is the initial step in the scientific method that involves gathering information and data about a phenomenon.

• Observation is a method used to test hypotheses after experiments are conducted.

• Observation is the final step in the scientific method where conclusions are drawn.

• Observation is a technique used to analyze data collected during experiments.

What is a scientific law?

• A statement that describes an observable phenomenon and is universally accepted as true.

• A hypothesis that has not yet been tested.

• An opinion that varies from person to person.

• A theory that explains a wide range of phenomena.

What is an independent variable?

• The variable that is measured in an experiment.

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

• The constant factor that remains unchanged throughout the experiment.

• The outcome that is affected by the independent variable.

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 accurate than quantitative data.

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

What is a hypothesis?

• A hypothesis is a guess about the outcome of an experiment.

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

• A hypothesis is a statement that cannot be tested.

• A hypothesis is a conclusion drawn from data.
