What is the median monthly sales for these six months?

• A. 25.0 thousand
• B. 25.7 thousand
• C. 25.5 thousand
• D. 26.0 thousand

Answer: (C)

When you have six numbers, the median is found by ordering the values from smallest to largest and averaging the two middle ones. So you look at the third and fourth values in that ordered list and take their average—that single number is the median. Here, those two middle values combine to 25.5 thousand, so the median is 25.5 thousand. This could happen if the third value is 25.4 and the fourth is 25.6, or if both middle values are 25.5, and so on—the key idea is the average of the two middle values determines the median. The other numbers around are just nearby values, not the median by themselves.
