Abstract: The technologies described herein use a statistical test to determine whether differences between data sets of buckets in a bucket test, such as differences between averages of two buckets (e.g., differences between means of two buckets), are directionally larger than a predetermined or preset minimum threshold value. The statistical test may also provide an extension to specify the minimum threshold value as a percentage. Also, described herein are techniques for estimating different control variables of a bucket test, such as estimating minimum bucket size to provide sufficient statistical power with use of the minimum threshold value.
