The experiment is run for a period of time and based upon an expected allocation of users into the A group (control group) and the B group (e.g., treatment group), along with an actual number of users directed into the two groups, it is determined if a minimal detectable error of allocation has been exceeded and, if it has, the data is deemed to be invalid. If not, the data is deemed to be valid.
