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.
What are neurons? What is the brain made of? The bulk of the brain is made up of structural cells termed glial cells and astrocytes. Lying in amongst these cells are neurons, specialized cells that conduct electrical impulses along their processes. It has been estimated that the average human brain contains about 100 billion neurons and, on average, each neuron is connected to 1000 other neurons. This results in the generation of vast and complex neural networks that are the mainstay of the brain's processing capabilities.
