Dr. Elena and Dr. Ravi are investigating the efficacy of a mandatory three-day "digital detox" weekend retreat on reducing cognitive fatigue among professional esports competitors. Dr. Elena plans to gather quantitative data by measuring participants' reaction times on a computerized performance task and using a 10-point closed-rating scale for self-reported mental exhaustion. In contrast, Dr. Ravi proposes collecting qualitative data by conducting semi-structured, one-on-one interviews to explore the players' lived experiences of being disconnected from technology and their feelings of competitive pressure.
Evaluate the advantages and disadvantages of using quantitative and qualitative data when conducting research into psychological issues. Make reference to the context of Dr. Elena and Dr. Ravi's study in your answer.
