💡 Analysis & Explanation
[Statistical Concept Definition]
In statistics, the 'range' of a dataset is defined as the absolute mathematical difference between the highest (maximum) value and the lowest (minimum) value present in the set.
[Data Evaluation]
Analyzing the given scores {45, 67, 80, 56, 72}, we identify the maximum score achieved is 80, and the minimum score recorded is 45.
[Final Computation]
Applying the formula: Range = Maximum Value - Minimum Value = 80 - 45 = 35.
Conclusion
The exact calculated range of the marks is 35.
