WebMay 20, 2024 · A symmetric distribution will always be symmetric about its median, which will also be equal to the mean (assuming this exists). If the distribution is unimodal then the mode will also fall at this point, but if the distribution is multimodal then the mode might occur elsewhere. WebBecause the standard normal distribution is symmetric with a mean of zero, the same proportion of the population that is less than some positive z is also greater than the same negative z.
