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)  spread should be described with the IQR because the distribution will be symmetric. B)  The spread should be described with the IQR because the distribution will be skewed to the right. C)  The spread should be described with the standard deviation because the distribution will be symmetric. D)  The spread should be described with the standard deviation because the distribution will be skewed to the right.
