Question 6

Dr. Vance is evaluating the effectiveness of a new wearable biofeedback device designed to reduce occupational stress among high-pressure financial traders. He recruited his sample of traders using a volunteer sampling technique by posting an invitation on an online forum for financial market analysts.

He allocated the volunteers to two conditions:

  • Condition A: The device provides real-time haptic biofeedback (gentle vibrations) during elevated heart rate episodes, guiding the user through deep-breathing exercises.
  • Condition B: The device functions only as a passive monitor, logging heart rate data without alerting the user.

Explain one weakness of Dr. Vance using a volunteer sampling technique for this investigation.
