Hi guys,
I'm trying to create an in-workspace view of statistical significance, using a Z-Score to compare the conversion rates of two dimensions.
Unfortunately, I can't think of how to format a freeform table to provide a single Z-Score to then check for significance, can anyone help or do they have any examples?
Cheers in advance!
You should be able to find the z-score:
(treatment rate - control rate) / standard deviation of population
There is an SD function there.
Then you create a calculated metric with the Cdf-z function: 1 - Cdf-z(z-score) that should give you the cumulative probability (i.e. Confidence value) that you're looking for.
