I have two continous samples: background and data. I want to check whether data observations are significantly greater than background. I used U-Test to calculate p-value, but now I want to find a pair of background/data with the biggest
background >> data between them.
In practice I have a formula to which calculates some stuff and return one value per observation. I want to show that if I apply this formula the result is significantly bigger for relevant data (non-background) and then among 6 formulas I want to choose the one which gives a biggest difference in results.
