• What is correlational research?

  A non-experimental method measuring two variables
• What does correlational research assess?

  The relationship between two variables
• Why is correlational research useful?

  It examines relationships without cause and effect
• How does correlational research compare to experimental research in terms of cost and time?

  It is cheaper and less time-consuming
• What types of topics can correlational research investigate?

  Difficult topics hard to experiment on
• What is a negative correlation?

  As one variable increases, the other decreases
• What are the three types of correlation?

  • Positive correlation: both variables increase together
  • Negative correlation: one variable increases while the other decreases
  • Zero correlation: no relationship found
• What is a positive correlation?

  As one variable increases, the other increases
• What does zero correlation indicate?

  No relationship found between variables
• What limitation does correlational research have regarding cause and effect?

  It cannot establish cause and effect
• What might affect the results of correlational research?

  A third variable or other factors
