Answer:
(B) Median and IQR.
Explanation:
In the image, we are presented a box plot, which has the minimum, lower quartile, the median, the upper quartile and the maximum. In order to find the median, we would need to add all of the scores (which are dots in the graph) and then divide it by the number of it. However, a box plot does not show to exact scores that all team members of the two teams got. Therefore, we are unable to find the mean with this. Standard deviation is where a set of dot data leans, which is not displayed in the image too. So, the answer is B.
