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. There are four scores below and four above the value 8. So 8 represents the mid point or the central tendency of the sample.

Biliary Disorders and Bile Duct Cancer. The biliary duct system is responsible for storing and transporting bile, a yellowish digestive fluid produced in the liver. The bile ducts are the tubes from which bile flows out from the liver. Bile ducts come together like the branches of a tree.The largest duct is called the common bile duct. Before bile is transported to the small intestine to aid in the digestive process, it is collected and concentrated in a storage container called the gallbladder.iliary Stricture. A biliary stricture is a narrowing of the common bile duct. When this happens, bile can back up into the liver, causing abdominal pain, nausea, itching, fever, chills, and jaundice. Strictures can be caused during surgery on nearby tissues, such as the gallbladder.
