When working with a large data set, it can be useful to represent the entire data set with a single value that describes the middle or average value of the entire set. In statistics, that single value is called the central tendency and mean, median and mode are all ways to describe it.o find the variance in a data set, subtract each number from the mean, and then square the result. Find the average of these squared differences, and that is the variance in the group. In our original group of five servers, the mean was 99.
Brain Shunt. A brain shunt is a narrow piece of tubing that is inserted into the brain in the fluid-filled ventricle. The tubing is then passed under the skin into another area of the body, most often into the abdomen.Occasionally, the shunt tubing can be placed into one of the chambers of the heart or the lining of the lungs. brain shunt is a narrow piece of tubing that is inserted into the brain in the fluid-filled ventricle.
It depends. Most Ventriculoperitoneal ( VP for short) shunts may be implanted for life for the treatment of hydrocephalus ( excessive cerebral spinal fluid, or CSF, build up in the brain ). The type of shunt and the health problem it is treating will ultimately determine the length of implantation. It depends.
