WebJul 30, 2024 · In a normal distribution, data is symmetrically distributed with no skew. Most values cluster around a central region, with values tapering off as they go further away from the center. The mean, mode and median are exactly the same in a normal distribution. Example: Normal distribution WebThe normal distribution is described by the mean ( μ) and the standard deviation ( σ ). The normal distribution is often referred to as a 'bell curve' because of it's shape: It is symmetric, meaning it decreases the same amount on the left and the right of the center.
