Normally distributed random numbers 翻译
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… WebIn a college entrance exam, the participants are rated as excellent, very good, good, and fair.
