Scientific Investigation Quiz

What is the first step of the scientific method?

• Ask a question or identify a problem

• Draw a conclusion

• Collect data

• Form a hypothesis

What is a hypothesis?

• A hypothesis is a proposed explanation or prediction that can be tested through experimentation or observation.

• A hypothesis is a conclusion drawn from personal opinion rather than scientific investigation.

• A hypothesis is a random guess with no basis in evidence.

• A hypothesis is a proven fact that does not require any testing.

What is data collection?

• The process of storing and organizing data

• The process of analyzing and interpreting data

• The process of deleting and removing data

What is the purpose of experimental design?

• The purpose of experimental design is to waste time and resources.

• The purpose of experimental design is to confuse researchers.

What is the difference between qualitative and quantitative data?

• Qualitative data is descriptive and subjective, while quantitative data is numerical and objective.

• Qualitative data is collected through surveys and questionnaires, while quantitative data is collected through observations and experiments.

• Qualitative data is based on opinions and feelings, while quantitative data is based on facts and figures.

• Qualitative data is numerical and objective, while quantitative data is descriptive and subjective.

What is a control group in an experiment?

• A control group in an experiment is a group that receives the experimental treatment.

• A control group in an experiment is a group that is used as a baseline for comparison.

• A control group in an experiment is a group that is excluded from the experiment.

• A control group in an experiment is a group that is used to test the hypothesis.

Why is it important to have a large sample size in data collection?

• To increase bias and inaccuracies in the results.

• To decrease reliability and generalizability of results.

• To save time and resources.

• To increase reliability and generalizability of results.
