Experimental Method

• What is the experimental method?

  A systematic approach to testing hypotheses
• What does "RCY" refer to in the context of the experimental method?


  It is likely a typographical error or abbreviation not defined in the material
• What is a hypothesis in an experiment?

  A testable prediction about the relationship between variables
• What is the difference between an aim and a hypothesis?

  An aim states the purpose of the experiment, while a hypothesis predicts the outcome
• What are the key components of an experimental method?

  • Independent and dependent variables
  • Operationalisation of variables
  • Types of hypotheses (directional or non-directional)
• How do you operationalize variables in an experiment?

  By defining how each variable will be measured or manipulated
• What are the two types of hypotheses mentioned?

  Directional and non-directional hypotheses
• How do the concepts of "Fits and Hits" relate to hypothesis testing?


  They refer to the accuracy of predictions made by the hypothesis
• What does "Bringing it all together" imply in the context of the experimental method?

  It suggests integrating all components of the experiment for a cohesive understanding
• What is the purpose of the "CHECK IT" section in the study material?

  To assess understanding of key concepts
• What is the mark allocation for explaining the difference between an aim and a hypothesis?

  1 mark
• What does "operation of the IV" refer to in an experimental method?

  It refers to how the independent variable is manipulated during the experiment
• What are dependent and independent variables?

  Independent variables are manipulated, while dependent variables are measured
• What is the significance of distinguishing between directional and non-directional hypotheses?

  It affects how the hypothesis is tested and interpreted
• How do "Fits and Hits" contribute to evaluating hypotheses?

  They help assess the accuracy of the predictions made
