A normal distribution is a bell-shaped distribution. Theoretically, a normal distribution is continuous and may be depicted as a density curve, such as the one below. The distribution plot below is a standard normal distribution . A standard normal distribution has a mean of 0 and standard deviation of 1. This is also known as the z distribution.
