Sampling

• What is the main topic of the video?

  Sampling in research methods
• Why is it important to consider the participants in a study?

  To determine if findings can be generalized
• What are the five sampling techniques discussed?

  • Random sampling
  • Systematic sampling
  • Stratified sampling
  • Opportunity sampling
  • Volunteer sampling
• What is the definition of target population?

  All individuals in the group to study
• What is generalization in research?

  Applying results from a sample to the population
• What is random sampling?

  Everyone has an equal chance of selection
• How can a researcher select participants randomly?

  Using a random number generator or drawing names
• What is a strength of random sampling?

  It avoids researcher bias in selection
• What is a potential weakness of random sampling?

  It may result in an unrepresentative sample
• What is systematic sampling?

  Selecting every Nth person from a list
• How does systematic sampling reduce bias?

  It removes the chance of researcher bias
• What is a limitation of systematic sampling?

  It may still produce an unrepresentative sample
• What is opportunity sampling?

  Including anyone available to participate
• What is a strength of opportunity sampling?

  It is a fast way to gather a sample
• What is a major drawback of opportunity sampling?

  It can lead to researcher bias in selection
• What is a volunteer sample?

  Participants select themselves to join
• What is a strength of volunteer sampling?

  It can reach a large number of participants
• What is a potential issue with volunteer sampling?

  It may lead to volunteer bias in results
• What is stratified sampling?

  A sample that represents subgroups of a population
• How does stratified sampling work?

  Participants are randomly selected from identified strata
• What is a major advantage of stratified sampling?

  It creates a representative sample of the population
• What is a limitation of stratified sampling?

  It can be time-consuming and complex
• What does WEIRD stand for in psychology research?

  • Western
  • Educated
  • Industrialized
  • Rich
  • Democratic
• Why is the WEIRD sample a concern in psychology?

  It may not generalize to the global population
• What is a criticism regarding historical psychology studies?

  They often ignored or underrepresented women
• What are the implications of bias and generalization in sampling?

  • Researcher bias affects participant selection
  • Volunteer bias limits participant diversity
  • Generalization may not apply to all populations
