WebbIt’s quite ironic really, sometimes, a normal distribution isn’t exactly the normal thing in the real world. Sure, with enough data we may end up leveraging the law of large numbers and tend to “normal” — but in some real-life scenarios (such as in finance), we may not have much data and the distribution is likely skewed.
