What is the median of the following set of scores? 18, 6, 12, 10, 147 (a) 10

(b) 14

(c) 18

(d) 12

✅ Correct option: (d) 12

Explanation:

The median is the middle value in an ordered set of data. To find the median, scores must first be arranged in ascending or descending order. Given scores: 18, 6, 12, 10, 147 Arranged in ascending order: 6, 10, 12, 18, 147 Since there are five scores (an odd number), the median is the third score in the ordered list, which is 12. The median is particularly useful when data contain extreme values or outliers, such as 147 in this dataset. Unlike the mean, the median is not affected by unusually large or small values, making it a more accurate measure of central tendency in skewed distributions.
