What does this 13.4 tells us?

It gives us a rough estimate of how is the spread of our dataset.

As per the formulation, it is the difference between first and third quartile, which is helpful in figuring out how is the middlespread of our data. Because that’s all what we care, as we can say that this specific range will not have any outliers, and hence gives us a proper insight of how the data is spreaded.
