Normal Probability Plot

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
