The Normal Distribution

Normal distribution Properties, proofs, exercises normal distribution

The Normal distribution is used to analyze data when there is an equally likely chance of being above or below the mean for continuous data

normalization 5 Normal or Gaussian Distribution Normal or Gaussian distribution is a continuous probability distribution that has a bell-shaped probability density function The Probability Density Function for a Normal X ∼ N is: f X = 1 σ 2 π e − 2 2 σ 2 Notice the x in the exponent of the PDF Sample size has a significant effect on sample distribution It is often observed that small sample size results in non-normal distribution This is a result of
