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.
What does Âµg mean? Tuesday July 29, 2014 at 12:49pm. Âµg is the correct symbol for the metric measurement microgram which is one millionth of a gram or one thousandth of a milligram. The symbol for Âµ is a Greek letter (mu) which means 'small'. Due to the symbol Âµ being typographically unavailable much of the time i.e. you cannot type it on a keyboard, other versions were devised; two of which are ug and mcg and are now widely used in its place.
