- warfangle 18y agoThey'd have to make the changes to 10 stores to hit 1%. Just nitpicking, though :)
- gojomo 18y agoMy understanding is that major walk-in retailers like Wal-Mart do multivariate testing to maximize the conclusions they can draw from simultaneous experiments. Apparently an approach called 'taguchi split testing' is especially valuable for evaluating combinations of changes, and is also applied in online situations that go beyond simple A/B testing.
