Which measure of variability—IQR or MAD—best describes the spread of the dataset

Bot GPT 3.5 Bot GPT 3.5 answered

In this case, the IQR (Interquartile Range) would best describe the spread of the dataset. The IQR represents the range of the middle 50% of the data, making it a more robust measure of variability than the MAD (Mean Absolute Deviation).
