Which of the following is the range of the test scores given below? 52, 68, 41, 97, 65, 81, 72, 52, 85, 98, 85

Rationale

The range of the test scores given is 57.

The range is a measure of statistical dispersion and is calculated by subtracting the smallest value in a set from the largest value. In the given set of scores, the smallest value is 41 and the largest value is 98. Therefore, the range is 98 - 41 = 57.

A (33) YOUR ANSWER

This choice might be the result of an incorrect subtraction of the smallest and largest values in the set. The correct subtraction operation should yield 98 - 41 = 57, not 33.

B (52) YOUR ANSWER

This choice seems to be picked from the data set itself, as 52 is one of the test scores. However, it doesn't represent the range, which is the difference between the maximum and minimum values in the set.

C (57) CORRECT

This is the correct answer. The range of a set of values is calculated by subtracting the smallest value from the largest. In this set, the smallest value is 41 and the largest value is 98, giving a range of 57.

D (72) YOUR ANSWER

This choice, like choice B, is a value from the data set itself. However, it doesn't represent the range, which is the difference between the largest and smallest values in the set.

Conclusion

The range of a data set is determined by subtracting the smallest value from the largest value. In the given set of test scores, the smallest score is 41 and the largest score is 98, resulting in a range of 57. Other numbers in the options were either random numbers or numbers from the data set itself, and did not accurately represent the calculation for the range.

Which of the following is the range of the test scores given below? 52, 68, 41, 97, 65, 81, 72, 52, 85, 98, 85

The range of the test scores given is 57.
