Normal Probability Plot,

Normal Goodness of Fit Test

Click the link below and save the following JMP file to your Desktop:

Proceed as in the Histogram tutorial to get the following JMP output:

Click the red down arrow next to **Percent **and select **Normal Quantile
Plot** (JMPs terminology for the Normal Probability Plot):

You should see:

**Goodness of Fit Test**

Click the red down arrow next to **Percent** and select **Continuous
Fit**, then select **Fit Normal:**

You should now see the following additional output on the far right:

Click the red down arrow next to **Fitted Normal Distribution** and select **Goodness
of Fit**:

You should now see:

The smaller the number under **Prob<W**, the less likely it is that
the data comes from a normal distribution.

In this case - since **Prob<W** is equal to 0.0002 - we see that the data
are not likely to have come from a normal distribution.
