# Properties of the Standard Normal Distribution

The normal distribution probability is specific type of continuous probability distribution. A normal distribution variable can take random values on the whole real line, and the probability that the variable belongs to any certain interval is obtained by using its density function. For the non-technical readers, a density is a function that allows to compute probabilities via integration on appropriate ranges, but for most practical applications, we can use software to skip the mathematical details. The main properties of a normally distributed variable are:
