IQR; the data distribution is skewed
Since the dataset includes a few values that are significantly higher than the majority of the data points, the best measure of variability to describe the spread of the data would be the Interquartile Range (IQR). MAD (Mean Absolute Deviation) would not be as effective in capturing the spread in this case because it gives equal weight to all data points, including outliers.

What was the year we started scientifically studying ice cores to learn about our past?
The scientific study of ice cores to learn about Earth's past began in the late 1950s. Specifically, the first successful collection of ice core samples for scientific research was conducted in 1956 by the U.S. Army Corps of Engineers during the construction of Camp Century in Greenland.
