Web[It's possibly you may have meant that for a symmetric distribution (let's assume the mean is finite), that the mean will be at the median. This is true but doesn't establish the case that mean=median implies symmetry, and as we saw there are counterexamples to the idea.] But let me return to your title question... Why: WebThe mean, median, and mode are all equal in the normal distribution and other symmetric distributions. However, when you have a asymmetric distribution, it affects the relationship between these measures of central tendency. The mean is sensitive to extreme values.

It is symmetrical, which means that the values on the left of the mean are the same distance from the mean as the values on the right. A normal distribution has a mean and a standard deviation that are both equal. 2. The distribution has only one peak, making it unimodal, which means that there is only one possible value. 3.

WebA symmetric distribution is a data visualization that appears virtually identical on both sides. It’s worth noting that the data doesn’t have to be identical on both sides to be termed symmetric; it only has to be close. Consider a mirror positioned in the midst of data distribution. Both sides should be almost exact replicas of one another.
