Question
### Understanding Box Plots

Box plots, also known as box-and-whisker plots, are a standardized way of displaying the distribution of data based on a five-number summary. This summary includes the minimum, first quartile (Q1), median (Q2), third quartile (Q3), and maximum.

Below is an illustration of a box plot with specific labels and a multiple-choice question designed to test your understanding of what each label represents.

#### Box Plot Diagram Description

The box plot shown includes several labeled points and segments:

- **A**: Located at the median (Q2) of the data set.
- **B**: Positioned at the third quartile (Q3).
- **C**: Positioned at the first quartile (Q1).
- **D**: Represents the Inter Quartile Range (IQR), which is the distance between the first (Q1) and third (Q3) quartiles.
- **E**: Indicates the minimum value in the data set.
- **F**: Designates two outliers above the upper whisker.

Outliers are plotted as individual points that fall outside 1.5 times the IQR above the Q3 or below the Q1.

#### Question and Options

What do the letters in the box plot above represent?

**a.**    
A = Mean, B = Upper Mean Quartile, C = Lower Mean Quartile, D = Inter Quartile Range, E = Minimum, and F = Outliers

**b.**    
A = Mean, B = Third Quartile, C = First Quartile, D = Inter Quartile Range, E = Minimum, and F = Outliers

**c.**    
A = Median, B = Third Quartile, C = First Quartile, D = Inter Quartile Range, E = Minimum, and F = Outliers

**d.**    
A = Median, B = Third Quartile, C = First Quartile, D = Inter Quartile Range, E = Mean, and F = Outliers

**Correct Answer: c.**    
A = Median, B = Third Quartile, C = First Quartile, D = Inter Quartile Range, E = Minimum, and F = Outliers

This exercise helps in understanding and interpreting the various components of a box plot, which is essential for data analysis and statistics.
