Law of Large Numbers: As you increase sample size (or the number of samples), then the sample mean will approach the population mean. The total area under the curve is 1 or 100%.

It is a type of normal distribution used for smaller sample sizes, where the variance in the data is unknown. In essence, it ensures that the distributions corresponding to different values of the parameters are distinct.
