A family of probability density functions whose mean, median and mode are identical. The function generates a symmetrical curve, whose position and shape is determined by its location and scale parameters, the mean and standard deviation respectively. The standard normal distribution has a location parameter of 0 and a scale parameter of 1.
Glossary Term
A volatile liquid prepared by fermentation of certain carbohydrates. Alcohol acts as a central nervous system (CNS) depressant, a diuretic, and a disinfectant. Although the exact mechanism of CNS depression is unknown, alcohol may act by inhibiting the opening of calcium channels, mediated by the binding of the inhibitory neurotransmitter gamma-amino butyric acid (GABA) to GABA-A receptors, or through inhibitory actions at N-methyl-D-aspartate (NMDA)-type glutamate receptors. Alcohol inhibits the production of antidiuretic hormone, thereby producing diuresis that may lead to dehydration. This agent kills organisms by denaturing their proteins.
