Normal Probability Plot
•Normal Probability Plot - provides a
good assessment for using the Normal
model on a set of data
•Arrange data from smallest to largest
•Record the percentile of the data for each value
•Use the Normal Distribution table to find the z-scores
•Plot each data point (x) against its z-score
•The straighter the line, the better fit the Normal model is
