Normal Distribution

#interview #statistics

Normal distribution is formed from Mean and Standard deviation
Mean identifies the mid point of the distribution and Standard deviation show how much to deviate from mean
Less the standard deviation, taller the curve
More the standard deviation, flatter the curve
For a normal distribution, Mean == Median == Mode

For bell curve, Mean = 0, Median = 1

Equation of Normal Distribution

$f (x) = \frac{1}{\sqrt{2 π σ^{2}}} \exp - \frac{(x - μ)^{2}}{2 σ^{2}}$
