Why is the Interquartile Range (IQR) considered a more robust measure of dispersion than the range?

A .The IQR uses the mean in its calculation, while the range does not.

B. The IQR can only be calculated for continuous data, while the range can be used for any data type.

C. The IQR measures the spread of the middle 50% of the data and is unaffected by extreme outliers.

D. The IQR is measured in squared units, making it more mathematically rigorous.
