Interpreting Box and Whisker Plots

A Box and Whisker Plot is a graphical representation of a dataset that displays its minimum, first quartile (Q1), median, third quartile (Q3), and maximum.

Subtract the first quartile (Q1) from the third quartile (Q3): IQR = Q3 - Q1.

The median is the middle value that separates the higher half from the lower half of the data.

To summarize and visualize the distribution, central tendency, and variability of a dataset.

A longer whisker indicates greater variability or spread in the data.

Upper Quartile (Q3).

Lower Quartile (Q1).

If the median line is closer to Q1 or Q3, the data is skewed in that direction.

A small IQR indicates that the data points are closely clustered around the median.

The five-number summary includes the minimum, Q1, median, Q3, and maximum.
