  • What is the definition of target population in research?
    Every individual that forms part of the group you plan to study
  • What is the goal of generalization in research?
    To apply results from a sample back to the target population
  • What is the key characteristic of random sampling?
    Every member of the population has an equal chance of being selected
  • How can a researcher create a random sample?
    By using a random number generator or drawing names from a hat
  • What is a strength of random sampling?
    It avoids researcher bias in participant selection
  • What is a potential weakness of random sampling?
    It may result in an unrepresentative sample
  • How does systematic sampling differ from random sampling?
    Systematic sampling selects every Nth person from a list
  • What is a strength of systematic sampling?
    It can be a quick way to get a sample with a small population
  • What is a potential drawback of systematic sampling?
    It may still produce an unrepresentative sample
  • What is an opportunity sample?
    A sample obtained by including anyone the researcher can easily access
  • What is a major advantage of using an opportunity sample?
    It is a fast way to gather participants
  • What is a significant disadvantage of opportunity sampling?
    It can lead to researcher bias and a non-representative sample
  • What is a volunteer sample?
    A self-selecting sample where participants volunteer themselves
  • What is a strength of volunteer sampling?
    It can reach a large number of potential participants through advertisements
  • What is a potential issue with volunteer sampling?
    It may lead to volunteer bias, as certain types of people are more likely to volunteer
  • What is the purpose of stratified sampling?
    To create a sample that is representative of the population as a whole
  • How is a stratified sample created?
    By identifying subgroups and randomly selecting participants from each subgroup
  • What is a major advantage of stratified sampling?
    It ensures the sample is representative of the larger population
  • What is a potential drawback of stratified sampling?
    It can be time-consuming and difficult to implement
  • What does WEIRD stand for in the context of psychology studies?
    Western, Educated, Industrial, Rich, and Democratic
  • Why is the concept of WEIRD participants a concern in psychology research?
    It raises questions about the generalizability of findings to the wider population
  • What is a criticism regarding historical psychology studies and gender bias?
    Many studies have ignored or underrepresented women
  • What are the strengths and weaknesses of the five sampling techniques discussed?
    Strengths:
    • Random: Avoids researcher bias
    • Systematic: Quick with small populations
    • Opportunity: Fast and easy to gather participants
    • Volunteer: Reaches a large number of participants
    • Stratified: Representative of the population

    Weaknesses:
    • Random: May be unrepresentative
    • Systematic: Possible unrepresentative sample
    • Opportunity: Researcher bias and limited representation
    • Volunteer: Volunteer bias
    • Stratified: Time-consuming and complex
  • What resources are available for students studying research methods in psychology?
    • Tutorial videos covering AS and A-level research methods
    • Worked examples for exam questions
    • Printable resources available on psych boost.com
  • Who can access the tutorial videos on psych boost?
    Patrons at the neuron level and above
  • What is the purpose of the support from patrons on Patreon for psych boost?
    It allows the creator to teach part-time and produce educational content
  • What is the next topic to be covered in the research methods video series?
    Experimental design
  • What is the definition of generalization in research?
    The process of applying results from a sample to the target population
  • What are the implications of researcher bias in sampling?
    It can lead to skewed results and affect the validity of the study
  • What are the implications of volunteer bias in sampling?
    It may result in a sample that does not represent the wider population
  • Why is it important to have a representative sample in research?
    To ensure findings can be generalized to the larger population
  • What role do advertisements play in volunteer sampling?
    They help researchers reach a larger pool of potential participants
  • Why is participant diversity significant in psychological studies?
    It ensures that findings are applicable to a broader population
  • What is the impact of historical biases in psychological research?
    It can lead to incomplete or skewed understandings of psychological theories
