During implementations of direct mailings, you often will run into the situation where you have to compare the results of different designs and implementations of a specific direct mail activity.

When you finally have the results of both of these implementations, in nearly every case you will have different results. And you will wonder how to compare them. This is the situation for that this little calculation has been built. After you entered the key-facts of your promotions, it will tell you if there is any statistical difference of the results.
