To identify which student reported 8 data points, we can count the number of entries for each student:
- Steven: 1, 1, 1, 1, 1, 2, 2, 2 (Total = 8 data points)
- Tomita: 0, 1, 1, 2, 2, 2, 2, 2, 3 (Total = 9 data points)
- Uriah: 1, 1, 1, 2, 3 (Total = 5 data points)
- Viktor: 1, 1, 1, 1, 2, 2, 8 (Total = 7 data points)
Based on the counts, Steven is the student who reported 8 data points.
