The normal distribution is a powerful tool that can be used to describe, understand, and make inferences about a wide variety of data.

Normal Random Variables (5 of 6) – Concepts in Statistics

We use a simulation based on the standard normal distribution to find probabilities. In this simulation, the numbers on the horizontal axis are z-scores.

Normal Distribution | Introduction to Statistics - JMP

The normal distribution is a theoretical distribution of values for a population. Often referred to as a bell curve when plotted on a graph.

Not everything in real life is normally distributed : r/AskStatistics

There are ways to make the normal distribution more flexible: skew-normal, mixtures of normals, and lots of other distributions like Weibull, ...

Z Score and Skewness: Navigating the Norms of Non Normality

A Z-score calculated for a high score in this distribution may not reflect the same level of rarity or extremeness as it would in a normally ...

Differences Between the Normal and Poisson Distributions

The normal distribution is so ubiquitous in statistics that those of us who use a lot of statistics tend to forget it's not always so common in actual data.

Lognormal and Normal Distribution - Investopedia

As long as the growth factor used is assumed to be normally distributed (as we assume with the rate of return), then the lognormal distribution makes sense.
