Intuitively this makes sense to me since if a data set is symmetric than for each point that is distance 'd' above the mean there will be a point that is distance 'd' below the mean (Although, in practice this is probably just very close to zero and actually …

Specifically it is the square root of the mean squared deviance from the mean. So the standard deviation tells you how spread out the data are from the mean, … WebGenerally, probability distributions can be categorised into two groups, i.e., symmetrical and asymmetrical distributions. A symmetrical distribution is a type of distribution whose probability density function or probability mass function is symmetric around its mean. The most famous example of the symmetric distributions is the normal ...

When we describe shapes of distributions, we commonly use words like symmetric, left-skewed, right-skewed, bimodal, and uniform. Not every distribution fits one of these descriptions, but they are still a useful way to summarize the overall shape of many distributions. Sort by:

A simple heuristic is to sample from a density which is like N (mean, sigma1) up to mean and like N (mean, sigma2) beyond mean. First sample a uniform [0, 1] variable and if it's less than 1/2, pick the first, otherwise pick the second. Then sample from the chosen normal distribution.
