How to approach this question
The range is calculated as the highest value minus the lowest value. For each data set, identify the maximum and minimum values and calculate the range. Compare the ranges to find the one that is different.
Full Answer
C.C✓ Correct
To find the range, you subtract the smallest value from the largest value in each set.
A: Largest = 8, Smallest = 2. Range = 8 - 2 = 6.
B: Largest = 6, Smallest = 0. Range = 6 - 0 = 6.
C: Largest = 9, Smallest = 5. Range = 9 - 5 = 4.
D: Largest = 5, Smallest = -1. Range = 5 - (-1) = 5 + 1 = 6.
The ranges for A, B, and D are all 6. The range for C is 4. Therefore, data set C has a different range.
Common mistakes
✗ Forgetting to order the data first to find the min/max (though not necessary for all sets here).\n✗ Making a mistake when subtracting a negative number (e.g., for set D).
