Hi,

The screenshot below is from an AB testing calculator that returns an MDE column (you can see it in action here). It's based on the data provided in the fields above it and in the left column.

I'd like to reproduce this functionality in a spreadsheet but am not sure of the formulas required for Excel.

Any help is greatly appreciated. Many thanks in advance.
