WebFeb 9, 2024 · The normal distribution is a continuous probability distribution that is symmetrical on both sides of the mean, so the right side of the center is a mirror image of … WebApr 23, 2024 · If a normal distribution has mean μ and standard deviation σ, we may write the distribution as N ( μ, σ). The two distributions in Figure 3.1. 3 can be written as. (3.1.1) N ( μ = 0, σ = 0) and. (3.1.2) N ( μ = 19, σ = 4). Because the mean and standard deviation describe a normal distribution exactly, they are called the distribution's ...
