Research issues

• What are extraneous variables in research?

  Variables that can affect the dependent variable
• What is the key to an experiment involving an independent variable (IV)?

  The IV must be manipulated to observe effects
• What should influence the dependent variable (DV) in an experiment?

  Only the independent variable (IV)
• What should be done with other variables that might interfere with the IV or DV?

  They should be controlled or removed
• What are additional unwanted variables called?

  Extraneous variables
• How should extraneous variables be identified in a study?

  At the start of the study by the researcher
• What is the effect of extraneous variables on the results of a study?

  They can muddy the findings of the study
• What is the relationship between confounding variables and the IV?

  They change systematically with the IV
• In a study with twenty participants, what should be done with the first ten participants?

  They should be used for the speed-up condition
• Why might participants be excited to see a specific individual in a study?

  They might see a celebrity or important figure
• What happens to the excitement level of participants as more arrive?

  Excitement may decrease as more arrive
• What does an unexpected event in a study indicate?

  It may lead to a second intended IV
• What should researchers consider when analyzing results?

  Whether the excitement was due to the drink
• What is the problem with emotional variables in a study?

  They can change systematically with the IV
• What is the main issue with confounding variables?

  They change systematically with the IV
• How can researchers ensure their findings are valid?

  By controlling confounding variables effectively
• What is the impact of confounding variables on research results?

  They can lead to incorrect conclusions
• What should researchers do if they suspect confounding variables?

  They should control or remove them
• What is the relationship between excitement and the drink in a study?

  Excitement may be influenced by the drink
• How can researchers determine if excitement affects results?

  By analyzing the relationship with the IV
• What is the main concern with emotional variables?

  They can confound the results of the study
• Why is it important to control for confounding variables?

  To ensure valid and reliable research findings
• What should researchers do if they find confounding variables?

  They should adjust their experimental design
• How do confounding variables affect the interpretation of results?

  They can lead to misinterpretation of data
• What is the effect of excitement on participant behavior?

  It can influence their responses in studies
• Why might researchers be uncertain about their findings?

  Due to potential confounding variables present
• What is the significance of controlling for emotional variables?

  It helps maintain the integrity of the study
• What is the primary goal of controlling extraneous variables?

  To ensure accurate results in research
• How do researchers minimize the influence of extraneous variables?

  By identifying and controlling them early
• What is the relationship between excitement and the study's findings?

  Excitement can affect the validity of findings
• Why is it crucial to control for confounding variables?

  To ensure the validity of the experimental results
• What is the main issue with confounding variables in research?

  They can lead to incorrect conclusions
• How can researchers ensure their findings are valid?
