Normal Distribution

Normal Distribution normal distribution A normal distribution is completely determined by its mean μ μ and its standard deviation σ σ , which means there are an infinite number of normal distributions normal distribution 5 Normal or Gaussian Distribution Normal or Gaussian distribution is a continuous probability distribution that has a bell-shaped probability density function

normal distribution 2 The mean, median, and mode are equal The middle point of a normal distribution is the point with the maximum frequency, which means that it possesses the

normal distribution If a set of n observations is normally distributed with variance σ2, and s2 is the sample variance, then s2σ2 has a chi-square distribution with n–1 This is the unshaded part of the graph from the mean to x 1 x 1 This is a normal distribution curve A value, x, is labeled on the Figure
