The appropriate interval width for a grouped frequency table depends on the number of intervals or categories desired, 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 scores, the distribution of the data, and the level of detail desired, rather than being directly determined by the range.
