What is the median of the following set of data: 25, 32, 18, 29, 20, 35?

✓ Correct Answer: Option B

To find the median, first arrange the data in ascending order: 18, 20, 25, 29, 32, 35. Since there is an even number of data points, the median is the average of the two middle numbers: (25 + 29) / 2 = 54 / 2 = 27.
