Question

for an engineering project, each student in mr. mcdonalds science class made measured how far it flung a marshmallow. this box plot shows the results.
marshmallow distance (in.)

1. what is the median?

20

1. what is the iqr?
2. what is the difference in medians?

Explanation:

Step1: Identify median from box plot

The median is the line inside the box of the first box plot, which aligns with 50 on the axis.

Step2: Calculate IQR (Q3 - Q1)

Q3 is the right edge of the box (70), Q1 is the left edge (30).
$\text{IQR} = 70 - 30 = 40$

Step3: Find medians of Team A/B, compute difference

Team A median = 3, Team B median = 7.
$\text{Difference} = 7 - 3 = 4$

Answer:

1. 50 inches
2. 40 inches
3. 4 units
