Webb13 apr. 2024 · Normal Distribution in R. Normal Distribution is a probability function used in statistics that tells about how the data values are distributed. It is the most important … WebbThe normal distribution is defined by the following probability density function, where μ is the population mean and σ2 is the variance . If a random variable X follows the normal distribution, then we write: In particular, the normal distribution with μ = 0 and σ = 1 is called the standard normal distribution, and is denoted as N(0,1).
