The appropriate interval width for a grouped frequency table depends on the number of intervals or categories you want to create, not directly on the range of the scores. The choice of interval width (e.g., 8 points) should consider factors like the total number of data points, the level of detail desired, and ease of interpretation, rather than being directly determined by the range (80 points in this case).
