Question: A psychologist has systematically observed that high stress levels and poor sleep quality regularly occur together. Apply the predictive goal of science to describe exactly how the psychologist can utilize this observed correlation in a new, specific clinical situation.

Sample answer: The psychologist can utilize the observed correlation to forecast whether poor sleep will occur in a specific patient who presents with high stress levels, making a prediction that has a significantly greater than chance accuracy.

Key points:

  • Use the systematically observed correlation to forecast future behaviors or events.
  • Apply the relationship to make a prediction in a specific situation.
  • Recognize that the applied prediction yields significantly greater than chance accuracy.

Rubric: Award full credit if the student explains that the psychologist can use the established correlation to forecast or predict one event based on the other in a specific situation, noting that the prediction will have greater than chance accuracy.
