The Powers of “Normal Distribution”

normal distribution  The Normal distribution is used to analyze data when there is an equally likely chance of being above or below the mean for continuous data  The normal distribution is maintained not only in Economic aspects but also in Biological aspects, Electrical Circuit, Physics, and many more

Statistical tables: Values of the Normal distribution  The normal distribution is a continuous probability distribution that is symmetrical around its mean with most values near the central peak

Statistical tables: Values of 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
