For more information, visit Matt's website http:... 4.4.2 - StatKey: Percentile Method. Regardless of the shape of the bootstrap sampling distribution, we can use the percentile method to construct a confidence interval. Using this method, the 95% confidence interval is the range of points that cover the middle 95% of bootstrap sampling distribution. The following examples use StatKey. A normal distribution is a bell-shaped distribution. Theoretically, a normal distribution is continuous and may be depicted as a density curve, such as the one below. The distribution plot below is a standard normal distribution . A standard normal distribution has a mean of 0 and standard deviation of 1. This is also known as the z distribution.Add up all the data values then divide by the number of data values.
