1. a) MEAN age of new additions: (46 + 57 + 76 + 44 + 76 + 65 + 57 + 69) / 8 = 490 / 8 = 61.25
b) MEDIAN age: Sort ages: 44, 46, 57, 57, 65, 69, 76, 76 → Median = (57 + 65) / 2 = 61
c) RANGE: 76 - 44 = 32
2. a) MEAN number of vials in stock: (4 + 7 + 1 + 2 + 5) / 5 = 19 / 5 = 3.8
b) MEDIAN: Sort counts: 1, 2, 4, 5, 7 → Median = 4
c) MODE: No mode (all values appear once)
d) RANGE: 7 - 1 = 6
3. a) MODE number of candies: 14 (appears twice)
b) MEDIAN: Sort counts: 7, 8, 9, 10, 10, 11, 12, 12, 13, 14, 14, 15, 16, 17, 18, 19, 20 → Median = 13
c) MEAN/AVERAGE: Sum = 228, Count = 17 → 228 / 17 ≈ 13.41
4. a) MEAN number of losses: (28 + 12 + 33 + 10 + 25) / 5 = 108 / 5 = 21.6
b) MEDIAN: Sort losses: 10, 12, 25, 28, 33 → Median = 25
c) MODE: No mode (all values appear once)
d) RANGE: 33 - 10 = 23
Parent Tip: Review the logic above to help your child master the concept of mean median mode 6th grade halloween printable.
