Suppose we have a distribution of the number of "friends" all users of a popular social media site have. What measure of spread would be best to describe this data?
A)The spread should be described with the standard deviation because the distribution will be symmetric.
B)The spread should be described with the IQR because the distribution will be symmetric.

The distribution of the number of "friends" on a social media site is likely to be skewed to the right, as a few users will have a very high number of friends, while the majority will have fewer.
