Question

Facebook data indicate that 50% of Facebook users have 100 or more friends and that the average (i.e., mean) friend count is 190. What do these findings suggest about the shape of the distribution of the per-user number of Facebook friends? Possibly generous hint: From the information above, could you estimate the median of these data?

Select one:

a. The distribution is left-skewed. (Mean < median.)
b. The distribution is symmetric. (Mean median.)

c. The distribution is right-skewed. (Mean > median.)

Explanation / Answer

The shape of the distribution is not symmetric because median is different from mean.

Median = 100

mean = 190

mean > median therefore the distribution is right skewed.
