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.
The Vasomotor Control Centre (VCC) is located in the medulla oblongata in the brain, and reg â¦ ulates the vascular shunt mechanism.This basically redistributes blood during exercise and at rest accordingly. This is actually located in the brainstem in particular the medulla oblongata. This is the primitive part of the brain which we have no concious control over (it is au â¦ tonomic) and ensures that we breathe above all costs (i.e. you can't forcibly hold your breath and suffocate yourself).
