Aims and Hypotheses

    Cards (22)

    • 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
    • Why might a researcher choose to investigate a specific aim?
      Previous research raised interesting questions
    • How should a researcher phrase an aim?
      As a clear statement or question
    • What is a hypothesis?
      A precise statement that can be tested
    • How does a hypothesis differ from a prediction?
      A hypothesis is a testable statement, not a prediction
    • What is the null hypothesis?
      It states there is no difference between conditions
    • What is the alternate hypothesis?
      It suggests there is a difference between conditions
    • What is the principle behind accepting the null hypothesis?
      It is accepted unless strong evidence rejects it
    • What is the role of statistical tests in hypothesis testing?
      They provide evidence to accept or reject hypotheses
    • What is a directional hypothesis?
      It states the expected direction of results
    • When would a researcher use a directional hypothesis?
      If previous research indicates the expected direction
    • What is a non-directional hypothesis?
      It states there is a difference but not the direction
    • Why should the word "prove" be avoided in scientific writing?
      Science is open to new evidence and falsifiability
    • What probability threshold is commonly accepted for the alternate hypothesis in psychology?
      One in 20 or less
    • What does accepting the alternate hypothesis imply?
      The evidence is strong enough, but not perfect
    • What are the two types of hypotheses in research?
      • Null hypothesis (H0): No difference between conditions
      • Alternate hypothesis (H1): Suggests a difference exists
    • What are the differences between directional and non-directional hypotheses?
      • Directional hypothesis: States expected direction of results
      • Non-directional hypothesis: States a difference exists, but not the direction
    • What is the importance of operationalizing variables in a hypothesis?
      • Clearly defines how variables are measured
      • Ensures clarity and precision in research
    • What is the significance of the term "falsifiability" in science?
      • A theory must be open to being proven false
      • Ensures scientific claims can be tested and challenged
    • What resources are available for patrons of psycboost?
      • Bonus resources
      • Tutorial videos
      • Access to a Discord channel
    • What is the role of evidence in hypothesis testing?
      • Evidence collected determines acceptance or rejection of hypotheses
      • Strong evidence leads to accepting the alternate hypothesis
