normal distribution

n
(Statistics) statistics a continuous distribution of a random variable with its mean, median, and mode equal, the probability density function of which is given by (exp-[(x–μ)2/2σ2]/σ√(2π)) where μ is the mean and σ2 the variance. Also called: Gaussian distribution

The red line is a Gaussian density (mean= 0.7 and SD= 0.03), which describes 58 % of the sample, and the green line is a Gaussian density (mean= 0.75 and SD= 0.025), which represents the 42 % of the sample.
