6. Normal probability plots
To make a Normal probability plot for a set of quantitative data:
•
•
Enter the data values in list D1 of the
Statistics 1Var app. We’ll use the state
unemployment rates data from page 122.
Define H1 as shown in the Symbolic view of
the app. (Tap
and select Normal
Probability for Plot1.)
•
Press V and select Autoscale to see the
finished graph.
Interpretation: The Normal probability plot is quite
linear, so it is reasonable to believe that the data
follow a Normal distribution.
