Good research questions

Design your research

• Read the report template (individual and in silence!)
  
  
• Choose a research question and formulate it correctly
• Formulate an hypothesis and support it with scientific reasoning
• Name the variables and describe how to manipulate them
  Include what data you need and how you intend to collect it
