the normal distribution is very commonly used. This is because it approximates many real will phenomena, given a large enough population size, the distribution off the heights off everyone in a population, the weights, the shoe ciders. Test scores follow a normal distribution very closely. It's also very easy for statisticians. Toe Walk with it has only to permit us the mean and the standard deviation. And with these two values, the percent does can easily be opting, given a value and vice versa. For example, if I know the mean and standard deviation off the distribution, given a new value X, I would be able to know its exact percentile within this distribution.
