WebThe normally distributed curve should be symmetric at the centre. There should be exactly half of the values are to the right of the centre and exactly half of the values are to the left of the centre. The normal distribution should be defined by the mean and standard deviation. The normal distribution curve must have only one peak. (i.e ... 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…
