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. The area under the curve of the normal distribution represents ...
WebIn a normal distribution, the mean, median and mode are equal. (i.e., Mean = Median= Mode). The total area under the curve should be equal to 1. The normally distributed curve … WebA normal distribution is continuous. A normal distribution is symmetric about its mean. The mean, median, and mode are equal for a normal distribution. The variance of normally distributed data is equally distributed about the mean. The graph forms a bell-shaped curve such that the maximum value is the mean.
