Aims and Hypotheses

    Cards (24)

    • What are the main topics covered in the video?
      Research aims and hypotheses
    • What is the difference between research aims and hypotheses?
      Aims outline what to investigate; hypotheses state testable predictions
    • What is an example of a research aim?
      To find out if colour can influence recall
    • Why might a researcher choose to investigate a specific aim?
      Previous research raised interesting questions
    • How can an aim be phrased?
      As a question or a statement
    • What is a hypothesis?
      A precise statement that can be tested
    • What must a hypothesis include in an experiment?
      Levels of independent variables and dependent variable
    • How would you operationalize the variable of recall?
      By stating the number of words recalled
    • What is the null hypothesis?
      It states no difference between conditions
    • When do scientists accept the null hypothesis?
      Unless evidence is strong enough to reject it
    • What is the alternate hypothesis also known as?
      Research hypothesis or H1
    • What does the alternate hypothesis suggest?
      There is a difference between conditions
    • What are the two ways the alternate hypothesis can be written?
      Directional and non-directional hypotheses
    • What does a non-directional hypothesis state?
      There is a difference but not the direction
    • What does a directional hypothesis indicate?
      It states the direction of the difference
    • When would a researcher use a directional hypothesis?
      If previous research indicates the direction
    • Why should the word "prove" be avoided in scientific writing?
      Science is open to new evidence and falsifiability
    • What probability threshold is accepted for the alternate hypothesis in psychology?
      One in 20 or less
    • What does accepting the alternate hypothesis imply?
      The evidence is strong but not perfect
    • What should you say instead of "prove" in essays?
      Evidence supports the theory
    • What are the types of hypotheses in research?
      • Null hypothesis (H0): No difference between conditions
      • Alternate hypothesis (H1): Suggests a difference exists
      • Directional hypothesis: Indicates the direction of the difference
      • Non-directional hypothesis: States there is a difference without direction
    • What is the process of hypothesis testing in research?
      1. Formulate null and alternate hypotheses
      2. Collect data
      3. Use statistical tests
      4. Evaluate evidence
      5. Reject or accept hypotheses based on evidence
    • What are the implications of using the word "proof" in scientific contexts?
      • Implies absolute certainty
      • Contradicts the principle of falsifiability
      • Misrepresents the nature of scientific inquiry
    • What resources are available for students on psycboost.com?

      • Bonus resources for Patreon supporters
