The normal distribution (often referred to as the “bell curve” is at the core of most of inferential statistics. By assuming that most complex processes result in a normal distribution (we’ll see why this is reasonable), we can gauge the probability of it happening by chance. To best enjoy this tutorial, it is good to come to it understanding what probability distributions and random variables are. You should also be very familiar with the notions of population and sample mean and standard deviation.
