73, 74, 75, 77, 79, 82, 84, 85, 91What is the median of the data shown?
Correct answer: C. 79
- A. m6q8z-1
- B. m5q9z2
- C. 79
- D. m20q12z-2
Explanation
The correct answer is 79. The median of a data set with an odd number of values is the middle value of the set when the values are ordered from least to greatest. Because the given data set consists of nine values that are ordered from least to greatest, the median is the fifth value in the data set. Therefore, the median of the data shown is 79
