In a symmetrical distribution mean is

WebIn fact, in any symmetrical distribution the mean, median and mode are equal. However, in this situation, the mean is widely preferred as the best measure of central tendency because it is the measure that includes all the values in the data set for its calculation, and any change in any of the scores will affect the value of the mean. WebIn a perfectly symmetrical distribution, the mean and the median are the same. This example has one mode (unimodal), and the mode is the same as the mean and median. In …

Finding the Mean of a Symmetric Distribution - TutorialsPoint

WebFeb 9, 2024 · The normal distribution is a continuous probability distribution that is symmetrical on both sides of the mean, so the right side of the center is a mirror image of the left side. The area under the normal distribution curve represents the probability and the total area under the curve sums to one. WebAn extremely common example of a symmetrical distribution is the normal distribution (bell-shaped curve). So the mean and median of a normal distribution are the same. Since a normal distribution is also symmetric about its highest peak, the mode (as well as the mean and median) are all equal in a normal distribution.
