Abstract

The case study and Decision: You are a data analyst advising a university-affiliated research and wellness initiative that is evaluating whether late-night smartphone use should be formally discouraged as part of student wellness guidance. Over the past academic year, administrators have raised concerns about declining sleep quality among students and its potential impact on academic performance, health, and decision-making. While smartphones are an essential tool for communication and learning, their use immediately before bedtime has emerged as a possible contributor to sleep disruption. The initiative must decide whether the available evidence is strong enough to justify recommending that students limit smartphone use before sleep. This decision must be made now, as the institution is preparing to update its wellness programming for the upcoming academic term.
