Question

7 from unit 3, lesson 11 which box plot has an iqr of 10? a b c d

Explanation:

Step1: Recall IQR formula

IQR = Q3 - Q1 (Q3=third quartile, Q1=first quartile; box edges)

Step2: Calculate IQR for A

Q1≈2, Q3≈12 → IQR≈10

Step3: Calculate IQR for B

Q1≈8, Q3≈11 → IQR≈3

Step4: Calculate IQR for C

Q1≈3, Q3≈11 → IQR≈8

Step5: Calculate IQR for D

Q1≈7, Q3≈10 → IQR≈3

Answer:

A. The box plot with Q1≈2 and Q3≈12 (topmost plot)
