Normal distribution mean median
In statistics, a normal distribution or Gaussian distribution is a type of continuous probability distribution for a real-valued random variable. The general form of its probability density function is The parameter is the mean or expectation of the distribution (and also its median and mode), while the parameter is its standard deviation. The variance of the dis… Webstatistical mean, median, mode and range: The terms mean, median and mode are used to describe the central tendency of a large data set. Range provides provides context for the mean, median and mode.
