**Question: 33**

**3.** What is the median of the following data set?

7, 17, 53, 23, 4, 2, 4

- A. 4
- B. 7
- C. 15.7
- D. 23

**Correct Answer:** B

**Explanation:**

The median is the central data point in an ordered list. Because this data set has seven numbers, the central point will be in the fourth position. Reordered, the list reads: 2, 4, 4, 7, 17, 23, 53. Thus, the median is 7. **Choice (A)**, 4, is the mode while **choice (C)**, 15.7, is the mean.
