What measure of spread is least by the long tail in the graph?

IQR

Step-by-step explanation:

Interquartile range (IQR): it's the difference between the largest and smallest values in the middle 50% of a set of data. It is not affected by the long tail in the graph because its calculation only consider the central part of data.

Range: it’s the difference between the highest value and the lowest value in a data set. It is affected by long tails because consider the whole data

Median absolute deviation (MAD): it's the median of the absolute deviations from the data's median. It's moderate affected by long tails because atypical measures give greater absolute deviation that may cause a greater MAD.
