Standard Normal Distribution

The standard normal distribution is a bell-shaped curve that represents how data points are spread around a middle value, called the mean. Most data falls close to the mean, with fewer points as you move farther away. It has a specific average of zero and a consistent spread, called standard deviation, of one. This distribution helps us understand probabilities and make predictions about data in many fields, such as science, finance, and social sciences, by providing a common reference for analyzing normally distributed data.
