The interquartile range (IQR) would be the best measure to describe the spread of this dataset. The IQR is less sensitive to outliers compared to the range, and in this case, there are some extreme values (such as 16.5, 17.6, and 18.0) that would have a large impact on the range. The IQR would give a better representation of the central spread of the data.
