1 answer

To find the range of each student's math quiz scores, we calculate the difference between the highest and lowest scores for each student.

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

  • Highest Score: 92
  • Lowest Score: 75
  • Range: 92 - 75 = 17

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

  • Highest Score: 93
  • Lowest Score: 72
  • Range: 93 - 72 = 21

Now, we will fill in the responses based on our calculations:

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 (a lower range indicates more consistency).
