Based on the box and whisker plot shown in the image, we can extract the following information:

• Median (Q2): The median is represented by the vertical line in the box. The value for the median appears to be 45.5.
• Least Value of the Second Group: The second group lies between the first quartile $Q_1$ and the median $Q_2$. The least value for this group would be at 34.7, the value of $Q_1$.
• Greatest Value of the Third Group: The third group lies between $Q_2$ and $Q_3$, and the greatest value of this group would be at 63.6, which is the value of $Q_3$.

Here's how you can fill out the answers in the boxes:

• Median = 45.5
• Least Value = 34.7
• Greatest Value = 63.6

Here are 5 related questions to deepen your understanding:

1. How are quartiles calculated from raw data?
2. What does the interquartile range (IQR) represent in a box and whisker plot?
3. How do outliers affect a box plot?
4. What is the significance of the whiskers in a box plot?
5. Can a box plot be used to identify skewness in data?

Tip: In box plots, the line in the middle of the box always represents the median, which splits the data into two equal halves.
