Which class has the greater range of quiz​ scores?
Mr. Park's class
Mr. Holmes's class

Answer 1

To determine which class has the greater range of quiz scores, we need to calculate the range for both classes. The range is defined as the difference between the highest and lowest scores in a dataset.

Mr. Park's Class:

• Low score: 56
• High score: 92

Range = High score - Low score = 92 - 56 = 36

Mr. Holmes's Class:

• Low score: 50
• High score: 74

Range = High score - Low score = 74 - 50 = 24

Comparison of Ranges:

• Mr. Park’s class range: 36
• Mr. Holmes’s class range: 24

Conclusion:

Mr. Park's class has the greater range of quiz scores.
