You are designing an experiment to test the effect of various offers on enrolling in a frequent flyer program. After collecting suggestions from colleagues, you wind up with the following conditions:

Control: Basic offer

Treatment 1: Offer with 1000 bonus points

Treatment 2: Offer with 1000 bonus points, 1 instant seat upgrade and a drink ticket.

Treatment 3: Offer with 1 instant seat upgrade and a drink ticket.

a. As you’re about to launch the experiment, one of your colleagues asks if they will be able to use your experiment to figure out whether it’s more effective to add an instant seat upgrade or a drink ticket to an offer. Will they, and if so, how?

b. Another colleague asks if they will be able to use your experiment to figure out the lift attributable to offering 1000 bonus points. Will they, and if so, how?
