Q & A

What is the main focus of the presentation?

The presentation analyzes the behaviors affecting daytime sleep among students, particularly how various factors influence their napping habits.

What are some key factors that the study examines?

The study examines factors such as travel time to university, sleep and wake times, study hours, caffeine consumption, stress levels, and pre-sleep activities.

How was data collected for the study?

Data was collected through an online questionnaire using Google Forms, which gathered numerical and aggregate data from 67 respondents, with 60 usable responses.

What challenges did the researchers face during data collection?

Challenges included misunderstanding of questions by respondents and difficulties in calculating certain data, which were addressed by providing clearer explanations and transforming data into more manageable formats.

What does the correlation coefficient of 0.07 indicate regarding napping and caffeine consumption?

A correlation coefficient of 0.07 suggests a weak positive relationship between daytime napping duration and daily caffeine consumption, influenced by many students consuming no caffeine.

What findings were observed concerning sleep and wake times?

The study found a positive correlation (0.43) between average bedtime and wake-up time, indicating that later bedtimes are associated with later wake times.

What was concluded about stress levels and average sleep hours?

The analysis showed a positive correlation (7.28) between daily stress levels and average sleep hours, indicating that higher stress is associated with more sleep.

How did the researchers assess the normality of the data?

The researchers used statistical tests to determine if the data followed a normal distribution, finding that average nap duration and sleep hours did not conform to normality.

What is the significance of the results regarding caffeine consumption?

The findings indicated that the average daily caffeine consumption does not follow an exponential distribution, suggesting a variability in caffeine intake among students.

What implications do the results have for student academic performance?

The insights from the study could inform strategies to enhance students' learning efficiency by addressing their sleep behaviors and managing factors like caffeine intake and stress.
