Quizplus · Accepted Answer

The normal distribution, also known as the Gaussian distribution, is a symmetrical, bell-shaped distribution that is commonly used to describe the probability distribution of many natural phenomena and chance occurrences. It is characterized by a central peak (mode) and symmetrical tails that extend out to infinity, with the majority of the data falling within one to three standard deviations of the mean. The normal distribution is an important concept in statistics and is used in many areas of research and analysis, including hypothesis testing, estimation, and data visualization.
