Figure 5.25 Example of an Equivalence Test
From Figure 5.25, notice the following:
• The Upper Threshold test compares the actual difference to 6.
• The Lower Threshold test compares the actual difference to -6.
• For both tests, the p-value is small. Therefore, you can conclude that the actual difference in means
(3.02) is significantly different from 6 and -6. For your purposes, you can declare the means to be
practically equivalent.
