Normal Distribution
Normal distribution, often depicted as a bell curve, describes how values are spread around a mean (average). In a normal distribution, most data points cluster around the center, with fewer points appearing as you move away from the mean in either direction. This pattern occurs in many natural phenomena, such as heights, test scores, and measurement errors. The curve is symmetric, meaning the left and right sides are mirror images. Understanding normal distribution helps in analyzing data, making predictions, and determining probabilities in various fields, including statistics, psychology, and economics.

Normal distribution, often called a bell curve, is a statistical concept where data points are symmetrically distributed around a central average. In a normal distribution, most observations cluster around the mean, with fewer values occurring as you move away from the center. This pattern appears in various phenomena, such as heights, test scores, or errors in measurements. The curve is defined by its mean (average) and standard deviation (which measures spread), allowing predictions about probabilities within a dataset. Understanding this distribution helps in analyzing real-world data and making informed decisions based on likelihoods.
