NATURE of SCIENCE REVIEW

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.

Why is it important to conduct background research before an experiment?

• It helps to understand existing knowledge, refine the research question, and design a more effective experiment.

• It allows researchers to skip the planning phase and jump straight into experimentation.

• It ensures that all experiments yield positive results.

• It is only necessary for complex experiments, not simple ones.

What is a variable in an experiment?

• A constant factor that does not change during the experiment.

• A factor that can exist in differing amounts or types and can affect the outcome of an experiment.

• A measurement that is always the same in every experiment.

• A type of equipment used to conduct experiments.

What is the role of a scientist?

• A scientist conducts research, formulates hypotheses, performs experiments, and analyzes data to expand knowledge in their field.

• A scientist primarily focuses on teaching and educating students about scientific concepts.

• A scientist's main job is to sell scientific equipment and materials to laboratories.

• A scientist only works in a laboratory setting without engaging in field research.

What is an experiment?

• A method of gathering data without any manipulation of variables.

• A scientific procedure undertaken to test a hypothesis by manipulating variables and observing the effects.

• A way to analyze past data to predict future outcomes.

• A casual observation made during a scientific study.

What is the importance of repeating experiments?

• It helps to verify results, ensure reliability, and identify any errors or anomalies.

• It allows researchers to publish their findings faster.

• It reduces the need for peer review.

• It guarantees that the results will be accepted by the scientific community.

What does it mean to collect data in an experiment?

• Gathering information through observation or measurement during an experiment to analyze and draw conclusions.

• Recording the hypothesis before starting the experiment.

• Performing calculations to determine the results of the experiment.

• Creating a list of materials needed for the experiment.

What is the purpose of a conclusion in scientific research?

• To introduce new research questions

• To summarize the findings of the research, indicating whether the hypothesis was supported or refuted.

• To provide a detailed methodology of the research

• To list all the references used in the research

What is the scientific method?

• A systematic process for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.

• A random approach to solving problems without any structured methodology.

• A method used exclusively in laboratory settings for conducting experiments.

• A philosophical approach to understanding the universe without empirical evidence.

What is a control group in an experiment?

• A group that receives the treatment or intervention

• A group that does not receive the treatment or intervention, allowing for comparison with the experimental group

• A group that is randomly selected from the population

• A group that is used to manipulate the variables in the experiment
