You're gearing up to launch your personal shopper startup. You've got everything set to go and now all you need is a killer ad campaign. Your design team put their heads together and come up with two different ads. But, no one can agree on which ad is best and tempers are flaring. Some argue that one ad appeal more to the men while the other is more attractive to the women. You tell your staff to simmer down because you can design a survey that can help you find out. You randomly pick 50 men and 50 women and randomly assign the men to two groups of 25 each and the women to another two groups of 25 each. One group of the 25 men and one group of the 25 women are exposed to one of the two ads while the remaining group of the 25 men and group of 25 women are exposed to the other and then they answers questions about the ad including how likely they'd be to shop at your store.
