Scientific Method Quiz

Which of the following is the first step in the scientific method?

• Identify the area of research

• Collect information

• Identify the research question and formulate a hypothesis

• Design a research method to test the hypothesis

What is a hypothesis?

• A variable that is manipulated by the experimenter

• A precise and unambiguous statement that can be supported or refuted by experiment

• A method to collect and analyze data

• A graphical representation of data

Which variable is manipulated by the experimenter?

• Dependent variable (DV)

• Independent variable (IV)

• Qualitative variable

• Quantitative variable

What type of data deals with numerical information about the variables?

• Nominal data

• Ordinal data

• Qualitative data

• Quantitative data

For an experiment to be reliable, it must be:

• Repeated several times to ensure results are due to manipulation of variables

• Directly related to the hypothesis

• Able to measure the melting point of nichrome wire

• Able to display data in graphical form

What is the dependent variable (DV)?

• The element that is manipulated by the experimenter

• The element that is influenced by the independent variable and subsequently measured

• A precise and unambiguous statement that can be supported or refuted by experiment

• A method to collect and analyze data

Which of the following is NOT a step in the scientific method?

• Identify the area of research

• Collect information

• Formulate a theory

• Test the conclusion

What is qualitative data?

• Data that focuses on the descriptions of the characteristics of what is being studied

• Data that is numerical information about the variables

• Data that is displayed in forms appropriate to the data

• Data that is analyzed using graphical information

What is the purpose of the research question in an experiment?

• To guide the direction of the research and analysis

• To determine the final results of the experiment

• To provide a summary of the experiment

• To list all the materials needed for the experiment

Which of the following is NOT one of the steps to develop a research question?

• Identify the independent variable

• Identify the dependent variable

• Draft several research questions

• Conduct the experiment
