What is the 'Normal Distribution'. The normal distribution, also known as the Gaussian or standard normal distribution, is the probability distribution that plots all of its values in a symmetrical fashion, and most of the results are situated around the probability's mean. Values are equally likely to plot either above or below the mean.
Definition of a Mg. A milligram (mg) is a metric system unit that represents a thousandth of a gram. Because of its larger size, a mg is a more commonly used measurement than a mcg. One thousandth of a mg is one mcg, and 1,000 mcg equal one mg.
The basic metric unit of mass is the kilogram (kg). Kilograms are the only basic unit to contain a metric prefix. For quantifying small masses, grams (g) or milligrams (mg) are used instead.Micrograms (Âµg) are used in microbiology and other laboratory work for extremely small masses.he basic metric unit of mass is the kilogram (kg). Kilograms are the only basic unit to contain a metric prefix. For quantifying small masses, grams (g) or milligrams (mg) are used instead.
