Technologies are disclosed for determining validity of data obtained from an A/B experiment, where the experiment evaluates the desirability of a potential change at a website. 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.

The present invention relates to a one-hand lipstick container, which includes: a container main body having a cylinder stood at the center of a body and a center through-hole formed through the center of the cylinder; a container cover that is rotatably connected to the upper portion of the container main body and has an open inlet formed through the upper surface; a cover holder that is combined by a spiral with the outer side of the cylinder of the container main body in the container cover and vertically ascends/descends by rotational force of the container cover; a door that is hinged to the cover holder to open/close the upper portion of the cover holder, opens a passage when the cover holder descends, and closes the passage when the cover holder ascends; a lipstick housing that is combined by a spiral with the inner side of the center through-hole of the container main body in the cover holder, vertically ascends/descends by rotational force of the cover holder, and ascends/descends in the opposite directions to the ascent/descent directions of the cover holder; and an anti-rotation means that transmits the rotational force of the cover holder to the lipstick housing and vertically guides the lipstick housing to ascend/descend in the opposite directions to the ascent/descent directions of the cover holder.
