In statistics, a symmetric probability distribution is a probability distribution—an assignment of probabilities to possible occurrences—which is unchanged when its probability density function (for continuous probability distribution) or probability mass function (for discrete random variables) is reflected around a vertical line at some value of the random variable represented by the distribution. This vertical line is the line of symmetry of the distribution. Thus the probability of bei… Web1. 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.
