What is the range of her scores?

Rationale

The range of her scores is 120.

The range is calculated by subtracting the lowest score from the highest score. If her highest score is 180 and her lowest score is 60, the range would be 180 - 60 = 120.

A (100) YOUR ANSWER

This choice represents a value that is less than the correct range. A range of 100 would suggest the highest score is only 100 points above the lowest score, which does not align with the provided highest and lowest scores.

B (120) CORRECT

This is the correct calculation for the range. If the highest score is 180 and the lowest score is 60, then the range is indeed 180 - 60 = 120, confirming this choice as accurate.

C (440) YOUR ANSWER

A range of 440 implies that the difference between the highest and lowest scores is significantly larger than the actual difference in this scenario. This number does not reflect the correct calculation based on the given scores.

D (2,250) YOUR ANSWER

This choice indicates an even larger range than 440, which is impossible given the scores provided. A range of 2,250 would require an unrealistically wide gap between the lowest and highest scores, making this option incorrect.

Conclusion

The range of scores is a measure of the spread between the highest and lowest values in a dataset. In this case, with a highest score of 180 and a lowest score of 60, the correct range is 120. The other options do not accurately reflect the difference between the scores, underscoring the importance of precise calculations in statistical analysis.
