Z = (X – mean)/stddev, where X is the random variable. Basically, this conversion forces the mean and stddev to be standardized to 0 and 1 respectively, which enables a standard defined set of Z-values (from the Normal Distribution Table) to be used for easy calculations. A snap-sho...
A normal distribution is the bell-shaped frequency distribution curve of a continuous random variable. Visit BYJU’S to learn its formula, curve, table, standard deviation with solved examples.

The normal distribution is produced by the normaldensity function,p(x) =e−(x− μ)2/2σ2/σ√2π. In thisexponential functioneis the constant 2.71828…, is the mean, and σ is the standarddeviation. The probability of arandom variablefalling within any given range of values is equal...
Definition 1. If the random variable X has a pdf given by 𝑟(𝑥)=𝑥2𝜙(𝑥), then we say that X follows a bimodal-normal distribution, and it is denoted as 𝑋∼𝑁𝐵 (see [18]). Remark 1. Let W and U independent random variables with 𝑊∼𝜒2(3), a chi-sq...
