Normal curves, also known as bell curves, are symmetrical probability distributions that follow a specific mathematical pattern called the normal distribution.
Standard Deviation: A measure of how spread out data points are within a normal curve.
Central Limit Theorem: States that regardless of the shape of the original population distribution, if we take repeated random samples and calculate their means, those means will follow an approximately normal distribution.
Skewness: A measure indicating whether data is skewed to one side or another in relation to a normal curve.
