To find the range of the math quiz scores for each student, you subtract the lowest score from the highest score for each student.

Student 1's scores: 75, 80, 84, 79, 92, 86, 88, 86, 86, 90

  • Highest score = 92
  • Lowest score = 75
  • Range = Highest score - Lowest score = 92 - 75 = 17

Student 2's scores: 83, 85, 91, 93, 72, 85, 76, 80, 82, 89

  • Highest score = 93
  • Lowest score = 72
  • Range = Highest score - Lowest score = 93 - 72 = 21

Now we can write the conclusions based on the ranges:

The range of Student 1’s math quiz scores is 17. The range of Student 2’s math quiz scores is 21. Based on the range, Student 1 performed more consistently on the math quizzes, since a lower range indicates less variability in scores.
