Comparing Test Score Ranges

In a statistics class, the teacher recorded the scores of students from three different tests:

Test A: 85, 90, 78, 92, 88

Test B: 76, 82, 80, 75, 79

Test C: 92, 95, 89, 94, 91

Based on the scores from each test:

• Calculate the range of scores for each test.
• Determine which test has the greatest range and which test has the least range.

In a quantitative comparison, compare the range of scores between Test A and Test B.
