Normal distribution - Wikipedia
It states that, under some conditions, the average of many samples (observations) of a random variable with finite mean and variance is itself a random variable—whose distribution converges to a normal distribution as the number of samples increases.

Normal Distribution | Definition, Uses & Examples - GeeksforGeeks
Normal distribution is a continuous probability distribution that is symmetric about the mean, depicting that data near the mean are more frequent in occurrence than data far from the mean.

Normal Distribution - Math is Fun
Data can be "distributed" (spread out) in different ways. But in many cases the data tends to be around a central value, with no bias left or right, and it gets close to a "Normal Distribution" like this: The blue curve is a Normal Distribution. follows it closely, but not perfectly (which is usual). because it looks like a bell.

What Is Normal Distribution Formula? - Cuemath
What Is a Normal Distribution Formula in Statistics? In order to be considered a normal distribution, a data set (when graphed) must follow a bell-shaped symmetrical curve centered around the mean.

Intuitively, the normal distribution is "nice" enough that we expect it to occur naturally unless there is a good reason to believe otherwise. This intuition is formalized by the central limit theorem, which states the following:

Formula for the Normal Distribution or Bell Curve - ThoughtCo
This formula is used for calculating probabilities that are related to a normal distribution. Rather than using this formula to calculate these probabilities directly, we can use a table of values to perform our calculations.

Among the amazing properties of the normal distribution are that the normal sum distribution and normal difference distribution obtained by respectively adding and subtracting variates and from two independent normal distributions with arbitrary means and variances are also normal!

Normal Distribution Equation - Statistics by Jim
The normal distribution formula gives the probability density for a given value of a continuous random variable (X). The normal distribution equation is the following: This formula returns the probability density, or height of the curve, at any given value of X, not a probability directly.
