      • question: do energy drinks affect mood or behaviour?
      • aim: investigate effectsof consuming energy drinks
      • hypothesis: can exist in 2 forms. Directional hypothesis- 'energy drinks will make a person talkative'. Non directional hypothesis- 'energy drinks will affect the degree to which a person speaks'
      • variables: factors in an experiment which can increase or decrease
      • independent variable: researcher directly alters themselves
      • dependent variable: depends on iv, it can be seen as results
      • operationalisation: turning a concept into something measurable
      • test: in this case a test could involve an experiment. using 2 conditions
        • 1) people who consumed the energy drink and asses how talkative they become
        • 2) participants consume water/ non energy drink and asses their talkative
      • results: presented in many ways- bar charts, graphs, etc. focus on quantative data (numbers) qualitative data is about how participants felt physically when consuming data
      • conclusion: finding now linked to the original hypothesis
