Grade 7 math · Fieldbook Learning

Name ______________________ Date __________

Subtract the means, then divide the difference by the MAD.

  1. Team A has a mean score of 16 and Team B has a mean score of 18.5. Both teams have a mean absolute deviation of 5. The difference between the means is how many times the MAD?
  2. Team A has a mean score of 26 and Team B has a mean score of 28. Both teams have a mean absolute deviation of 4. The difference between the means is how many times the MAD?
  3. Team A has a mean score of 33 and Team B has a mean score of 37. Both teams have a mean absolute deviation of 4. The difference between the means is how many times the MAD?
  4. Team A has a mean score of 27 and Team B has a mean score of 29. Both teams have a mean absolute deviation of 4. The difference between the means is how many times the MAD?
  5. Team A has a mean score of 26 and Team B has a mean score of 32. Both teams have a mean absolute deviation of 2. The difference between the means is how many times the MAD?
  6. Team A has a mean score of 38 and Team B has a mean score of 41. Both teams have a mean absolute deviation of 6. The difference between the means is how many times the MAD?
  7. Team A has a mean score of 21 and Team B has a mean score of 31.5. Both teams have a mean absolute deviation of 7. The difference between the means is how many times the MAD?
  8. Team A has a mean score of 15 and Team B has a mean score of 27. Both teams have a mean absolute deviation of 8. The difference between the means is how many times the MAD?
  9. Team A has a mean score of 31 and Team B has a mean score of 46. Both teams have a mean absolute deviation of 10. The difference between the means is how many times the MAD?
