testing stratified sampling: july 17, 2020

key research strategy

Create “Treatment” groups by selecting unique samples of customers

Stratified sampling to produce Comparison groups

Monitor divergence between “Treatment” and Comparison Groups (both pre- and post-COVID

These “Treatment” groups are not program participants (which is good)!

phase 1: stratified sampling and pre-covid testing

Goal: Develop and Demonstrate successful implementation of stratified sampling

• What parameters can/should be used
• Develop codebase and test/refine
• Multidimensional stratification

Question: What does it take (binning schemes) to create equivalency between treatment and comparison?
