Interpret the key results for Distribution Plot

Complete the following steps to interpret a probability distribution plot.

Step 1: View the shape of the distribution

Use a probability distribution plot to view the shape of the distribution or distributions that you specified.

Each distribution has a unique curve. When you change the parameters of the distribution, you can see how the distribution curve changes.

Use this plot to compare different normal distributions when the mean and standard deviation values change.

Step 2: Compare distributions

Use a probability distribution plot to compare different distributions. For example, an engineer wants to know whether one distribution is approximately similar to other distributions under certain conditions.

Use this plot to compare a normal distribution and a t-distribution.

Step 3: Determine the probability of a shaded area

Use a probability distribution plot to determine the probabilities of specific data values within the distribution.

Minitab shades the region that you specify and provides the other values that you do not specify.

This plot show the probability of the shaded region, which is specified as a data value range.
