Point A is plotted near the origin. The curve starts from point A and rises steeply upward and declines downward. Point B is plotted on the steep upward curve near the peak. Point C is plotted on the declining curve near the peak. The curve goes down to the level of point A and stretches to the right to join point D which is much farther away from the peak to the right.


A team of students were comparing the mean and median of a dot plot and noticed that the dots made a graph. They labeled the mean, median, minimum, and maximum of the graph. Which point is most likely the mean of the skewed data?

Answer 1

C

In a right-skewed distribution the mean is pulled toward the long right tail (to the right of the median). Point C is on the right side of the peak (toward the tail), so it is most likely the mean.
