Experimental design

• What topic does the video cover?

  Experimental design in psychology
• What is the relationship between participant sample and independent variable?

  They are combined in experimental design
• What are the two experimental designs mentioned?

  Repeated measures and independent groups design
• What is a repeated measures design?

  All participants complete both conditions
• What is an independent groups design?

  Participants are split into different groups
• What is a potential issue with independent groups design?

  Participant variables may influence results
• How could participant variables affect a study on temperature and reaction times?

  Younger participants may skew the results
• What is a repeated measures design's main advantage?

  Eliminates participant variables affecting results
• What is a disadvantage of repeated measures design?

  Order effects may influence participant performance
• What is counterbalancing?

  A method to control order effects
• What does counterbalancing aim to achieve?

  Balance order effects across conditions
• How do the strengths of independent groups design compare to repeated measures design?

  Strengths of one are weaknesses of the other
• What is a matched pairs design?

  Two groups matched on a characteristic
• How are participants assigned in a matched pairs design?

  Based on a characteristic measured beforehand
• What is the main advantage of matched pairs design?

  Reduces participant variables and order effects
• What is a disadvantage of matched pairs design?

  It takes longer to set up than others
• What is a common issue with matched pairs design?

  Participants are similar but not identical
• What are the strengths and weaknesses of the three experimental designs discussed?

  Strengths:

  • Repeated measures: Eliminates participant variables
  • Independent groups: Simpler setup, no order effects
  • Matched pairs: Reduces participant variables and order effects

  
  

  Weaknesses:

  • Repeated measures: Order effects may occur
  • Independent groups: Requires more participants
  • Matched pairs: Takes longer to set up
• How many tutorial videos are mentioned for research methods?

  Six tutorial videos
• What resources are available for patrons at the neuron level and above?

  Access to tutorial videos and printable resources
• What is the website mentioned for additional resources?

  psychboost.com
• Who is thanked for supporting psych boost?

  Students and teachers on Patreon
• What is the purpose of the research methods unit?

  To provide exam tips and examples
• What is the significance of the support from patrons?

  It allows part-time teaching and content creation
• What is the next topic mentioned for the upcoming video?

  Variables
• Why is it important to understand participant variables in experimental design?

  They can influence the results of the study
• What are demand characteristics in repeated measures design?

  Participants may change behavior to please researchers
• What is the role of random assignment in matched pairs design?

  To ensure balanced participant characteristics
• How do order effects impact experimental results?

  They can skew performance based on sequence
• Why is balancing participant characteristics important in matched pairs design?

  To reduce the influence of participant variables
• What is the significance of statistical testing in analyzing related data?

  It helps determine the significance of results
