or

the normal curve is symmetrical about the mean μ; the mean is at the middle and divides the area into halves; the total area under the curve is equal to 1; it is completely determined by its mean and standard deviation σ (or variance σ2)the normal distribution is defined by the following equation: the normal equation. the value of the random variable y is: y = { 1/[ σ * sqrt(2π) ] } * e-(x - μ)2/2σ2. where x is a normal random variable, μ is the mean, σ is the standard deviation, π is approximately 3.14159, and e is approximately 2.71
