This tutorial first explains the concept behind the normal distribution, then it discusses h A normal distribution is symmetric about its mean, and most of the values in a normal distribution cluster around the mean, with 99.7% of the values lying within 3 standard deviations of the mean. The further away a value is from the mean, the less likely it is to occur. More specifically, for a continuous random variable that has a normal In the case of normalization of scores in educational assessment, there may be an intention to align distributions to a normal distribution. A different approach to normalization of probability distributions is quantile normalization , where the quantiles of the different measures are brought into alignment. A sample of data will form a distribution, and by far the most well-known distribution is the Gaussian distribution, often called the Normal distribution. The distribution provides a parameterized mathematical function that can be used to calculate the probability for any individual observation from the sample space. This distribution describes the grouping or the density of the observations .
