Range; the distribution is skewed, and there are outliers in the dataset.

In this case, the range would be more appropriate to describe the spread of the dataset since there are outliers present and the distribution is skewed. The interquartile range (IQR) would be better suited for a dataset with a symmetrical distribution and no outliers.
