Data spread in Normal Distribution

  • 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

[!def] Equation of Normal Distribution
f(x) = \frac{1}{\sqrt{2 \pi \sigma^2}} \exp-\frac{(x-\mu)^2}{2\sigma^2}
