This makes intuitive sense because when N = n, the sample Note that these values are taken from the standard normal (Z-) distribution. The area between each z* value and the negative of that z* value is the confidence percentage (approximately). For example, the area between z*=1.28 and z=-1.28 is approximately 0.80. Hence this chart can be expanded to

Where: p вЂ“ Sample Proportion (fraction of sample which is a success); Now to find the desired z score, you need to know the confidence interval of the sample because the Z score is dependent on that.Below table is given to see the relation of a confidence interval and z score: The Sampling check included with Data Reviewer allows you to create a sample set of features that are randomly selected from one or more layers.
