Almost all of the students' scores are below the average. Therefore, in this case the mean is not a good representative of the central tendency of this sample. The median, on the other hand, is the value which is such that half the scores are above it and half the scores below. So in this example, the median is 8.

Bile is a digestive fluid produced by the liver and stored in the gallbladder, and is used by the body to break down fats so they can be absorbed.

A bile duct leak can cause pain, inflammation and infection in the abdominal cavity where the bile has leaked.
