  1. How to Write Testable Questions

  2. What is a Testable Question? • A testable question is one that can be answered by designing and conducting an experiment.

  3. How Do You Write a Testable Question? • Testable questions always have the same format… How does Manipulated Variable affect Responding variable? • FYI… When determining whether a question is testable always identify the manipulated and responding variables first

  4. How to Turn a Non-Testable Question into a Testable Question Step 1: Read the question carefully. Which brand of shoe makes you run faster Nike or New Balance? • Ask yourself….. What‛s the manipulated variable? What‛s the responding variable?

  5. Turning a Non-Testable Questioninto a Testable Question Step 2: Determine the manipulated and the responding variable in the question. Question: Which brand of shoe makes you run faster Nike or New Balance? – Manipulated variable (What‛s being changed on purpose?): Brand of shoe – Responding variable (What‛s being measured?): How fast you run

  6. Turning a Non-Testable Questioninto a Testable Question Step 3: Plug the variables into the “How does____ affect ____?” format… How does manipulated variable affect responding variable? How does the brand of running shoe affect how fast you run?

  7. Practice Problem 1 • Non-Testable Question: • Does carbon dioxide in the atmospherecause the atmosphere to warm? Manipulated variable: ??? Carbon dioxide Responding variable: ??? Atmospheric temperature

  8. Practice Problem 1 • Non-Testable: Does carbon dioxide in the atmospherecause the atmosphere to warm? • Testable: How does the amount of carbon dioxideaffect atmospheric temperatures?

  9. Practice Problem 2 • Non-Testable: Is achievement in school higher when students are tested frequently? Manipulated Variable: ??? Responding Variable: ???

  10. Practice Problem 2 • Non-Testable: Is achievement in school higher when students are tested frequently? • Testable: How does the amount of testing affect student achievement?

  11. Writing Testable Questions Takes Practice • Our natural curiosities often produce existence questions which are broad and ill-defined for scientific investigations • Begin with existence questions and then focus on one factor • Practice, Practice, Practice!!!
