Normal Distribution

normal distribution  The sampling distribution of the mean becomes approximately normal regardless of the distribution of the original variable The sampling distribution of the 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

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 The sampling distribution of the mean becomes approximately normal regardless of the distribution of the original variable The sampling distribution of the
