Exercise and Sleep Quality Study

Researchers wanted to investigate whether there is a relationship between physical activity and sleep quality among young adults. They recruited 8 participants and collected the following data:

  • Weekly exercise (hours): The total time spent doing moderate-to-vigorous physical exercise in a typical week.
  • Sleep quality rating: A self-report rating of weekly sleep quality on a scale from 1 (very poor) to 10 (excellent).
