A box plot shows a box extending from 40 to 70 with a vertical line at 58, and whiskers at 25 and 90. What is the median?
Answer and explanation
Correct answer: B. 58 marks
- Step 1: In a standard box-and-whisker plot, the vertical line inside the box indicates the median (Q2). Step 2. The line is at 58, so the median is 58 marks. Answer: 58 marks. Why not the others: 40 marks is Q1; 55 marks is the midpoint of the box; 70 marks is Q3.
