Statistical formulas can be defined as the group of statistical symbols used to make a statistical statement. Here we will discuss popular formulas and what they stand for. Population Mean. The term population mean, which is the parameter of a given population, is represented by:Î¼ = (Ï X i) / N. The symbol âÎ¼â represents the population mean. The symbol âÏ X i â represents the overall sum of all variables present in the population (say, in this case) X 1 X 2 X 3 and so on.tatistical formulas can be defined as the group of statistical symbols used to make a statistical statement.

Human Brain Structure. The human brain is comprised of a number of different regions. Each of these regions are vitally important with highly specialized functions. The central part of the brain includes the brain stem and the midbrain. The function of the midbrain and has been largely preserved over years of evolution.
Anatomy and physiology of the brain and spinal cord. The brain is a spongy organ made up of nerve and supportive tissues. It is located in the head and is protected by a bony covering called the skull. The base, or lower part, of the brain is connected to the spinal cord.Together, the brain and spinal cord are known as the central nervous system (CNS).he blood-brain barrier is made up of very small blood vessels (capillaries) that are lined with thin, flat endothelial cells. In other parts of the body, endothelial cells have small spaces between them that allow substances to move in and out of the capillary so they can reach other cells and tissues.
