Which class has the greater range of quiz​ scores?

1 answer

To calculate the range of quiz scores for each class, we subtract the low score from the high score.

Mr. Park's Class:

  • Low score: 23
  • High score: 35
  • Range = High score - Low score = 35 - 23 = 12

Mr. Perez's Class:

  • Low score: 21
  • High score: 29
  • Range = High score - Low score = 29 - 21 = 8

Part 7 Answer: Mr. Park's class has the greater range of quiz scores, with a range of 12 compared to Mr. Perez's range of 8.
