F x of normal distribution
WebSeveral properties of the Normal distribution are worth noting: It is easy to see from the formula for \(f_X(x)\) that the distribution is symmetric around \(x = \mu\). By the properties of the mean, this confirms that \(\mu_X = \mathrm{E}(X) = \mu\). The pdf has one peak, which is at \(x = \mu\). WebUnlike a probability, a probability density function can take on values greater than one; for example, the uniform distribution on the interval [0, 1/2] has probability density f(x) = 2 for 0 ≤ x ≤ 1/2 and f(x) = 0 elsewhere. The standard normal distribution has probability density
