When three are plotted, the first one plots at the top, the second in the middle, and the third at the
bottom.
NormProbPlot
NormProbPlot (Ô) (normal probability plot) plots each observation X in Data List versus the
corresponding quantile z of the standard normal distribution. If the plotted points lie close to a
straight line, then the plot indicates that the data are normal.
Enter a valid list name in the
Data List field. Select X or Y for the Data Axis setting.
• If you select X, the TI-84 Plus plots the data on the x-axis and the z-values on the y-axis.
• If you select Y, the TI-84 Plus plots the data on the y-axis and the z-values on the x-axis.
