Was the treatment clustered?
No

Experiment Characteristics

Sample size: planned number of clusters
This is not a traditional cluster, but we assign client race, ethnicity, gender, and side of market to an individual subject. In this way, the experiment can be thought of as a 3x2x2 design, but the "clusters" are over-lapping.
Sample size: planned number of observations
29,498
Sample size (or number of clusters) by treatment arms
2458
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
Using a difference in proportions test, we anticipate being able to detect a minimum of a 10 percentage point difference in response in the smallest cell. In the overall response difference in the largest category we will be able to detect a minimum of a 1 percentage point difference in response.
