In a symmetrical distribution mean is
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. Have a blessed, wonderful day! WebNov 2, 2015 · Yes, they are equal to one another. Explanation: In a symmetric distribution, one half of the curve is the mirror image of the other half. The frequencies are distributed evenly. The pull is the same on both sides. Since one side balances the other, all the three measures fall exactly at the middle. Normal Distribution Answer link Ramchandran A.

Mode always exists but may not be unique i.e. we may get distributions which are not unimodal (i.e. multimodal). So, the conclusion is if we have a symmetric distribution whose mean exists and the distribution is unimodal then we can say. Mean = Median = Mode. Also mean, median and …
WebSymmetrical distribution is a statistical term that refers to a distribution of data that is mirror-image across a central value. The most common type of symmetrical distribution is the normal distribution, which is often represented by a bell curve. In a normal distribution, the mean, median, and mode are all equal. WebStep 1: Since the mean and median are the same in a symmetric distribution, find the middle number by removing the highest and lowest values and repeating until only one or two values remain. Step ...
