Data Collection Procedures:

a) Study Design: The data for this study were generated through a combination of surveys and wearable sleep monitoring devices. This approach involved both self-reporting by participants and objective measurement of sleep patterns through the devices.

b) Original Purpose: The original purpose of the data collection was to investigate the relationship between sleep patterns, lifestyle factors, and academic performance in college students. The study aimed to understand how variations in sleep duration and quality might impact students’ overall well-being and academic achievements.

c) Data Collection Method: The data collection involved two main methods:

d) Collection Timeframe: The data were collected over a period of six months, starting from January 2023 to June 2023. This timeframe was chosen to capture potential variations in sleep patterns across different seasons and academic periods.

e) Collection Location: The data were collected on the campus of the participating university. Participants were able to complete surveys online, and the wearable sleep monitoring devices were distributed and calibrated on-site. This ensured that the data accurately represented the sleep patterns and lifestyles of students within the university environment.

These data collection procedures were implemented to provide a comprehensive understanding of the factors influencing sleep in college students and to gather both subjective and objective measures for a more nuanced analysis. ```
