Using Probit Analysis to Test Promotional Effects on Sales

A retail company conducts an experiment to test the effects of different promotions (where the promotion is a percentage off the retail price) on online, from catalog, and in-store sales. The promotional offers are made to randomly selected patrons and they record the numbers of sales.

This information is collected in offer.sav. See the topic Sample Files for more information. Use the Probit Analysis procedure to construct a dose-response model for the promotional effects on sales.
