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 A Specific Normal curve is described by giving its mean and standard deviation ▫ Density curves are used to illustrate many types of distributions ▫ A standard normal distribution has a mean of 0 and standard deviation of 1 This is also known as the z distribution You may see the notation (N(mu, sigma
