Dr. Aris wanted to investigate whether there was a correlation between the time spent on social media the evening before an exam and a student's self-reported mindfulness focus level during the exam.
She randomly selected six students from a study group who logged their evening activities. At the end of the exam, she recorded their social media usage (in hours) from the night before and asked them to rate their mindfulness focus level.
Dr. Aris asked the students to rate their mindfulness focus level on a scale of 1 to 5 (where 1 was very unfocused and 5 was highly focused).
The results of Dr. Aris's study are shown in Table 1.
| Student | Social media usage (hours) | Mindfulness focus score |
|---|---|---|
| A | 3 | 2 |
| B | 1 | 5 |
| C | 4 | 2 |
| D | 2 | 4 |
| E | 5 | 1 |
| F | 3 | 2 |
Complete Table 2 and calculate Spearman's rank correlation coefficient between the social media usage hours and the self-reported mindfulness focus score. Round your final answer to two decimal places.
