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.
The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. The brain is located in the head, usually close to the sensory organs for senses such as vision. The brain is the most complex organ in a vertebrate's body. In a human, the cerebral cortex contains approximately 15â33 billion neurons,[1] each connected by synapses to several thousand other neurons.
