Your psychology teacher has read about mindfulness-based stress reduction techniques and wants to investigate its benefits.
She asks you to design a study to see if there is a correlation between weekly time spent meditating and physiological stress levels in college students.
You need to select a sample of 15 participants using volunteer sampling.
Your teacher tells you not to use self-report to measure stress levels and tells you to use a different, more objective way of measuring stress.
Suggest how you could measure the two co-variables, weekly time spent meditating and physiological stress levels, for your study.
