WebbA 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. WebbA normal distribution has two parameters (two numerical descriptive measures), the mean ( μ) and the standard deviation ( σ ). If X is a quantity to be measured that has a normal distribution with mean ( μ) and standard deviation ( σ ), we designate this by writing f(x) = 1 σ ⋅ √2 ⋅ π ⋅ e ( − 1 2) ⋅ (x − μ σ)2 bubly commercial
