IQR; the data distribution is skewed
IQR (Interquartile Range) is more appropriate for describing the spread of the data in this case because the dataset is skewed, with some higher values like 155, 174, 189, 200, 209, and 250. MAD (Mean Absolute Deviation) might not be as accurate in this scenario because it is sensitive to outliers, and this dataset has some outliers.
