With two kids it is hard to decide if they should be a part of the Treatment or Control Group. So why not spread your bets around and sign one kid up for the Control Group (to play it safe) while the other gets to be in the Treatment Group (for potential big returns)?


This listing is for two children's t-shirts or bodysuits (or one of each). One shirt will be screen printed with a blue "Control Group" design, while the other has a red "Treatment Group" design.
