I have two samples. River A and river B. The samples were collected to determine the effectiveness of phosphate in removing the pollution. The river A data is set in before and after treatment. Same goes for River B. What test should I do?

[@olowonilara1]

Paired sample t-test on A and B

[@funkymcnugget]

exactly what @olowonilara1 says. You have 2 independent samples (the rivers), but the effectiveness of phosphate is tested before and after. So its dependend. But then just for 2 random variables.

1. Dr. Hannah Volk-Jesussek says about standard error but "Err is human" whether this err is standard error or not.
2. How soft Austrians' psychology of sex against Indians' physiology of sex speaks is still a thought provoking subject.
3. Freud, Mesmer are my inspiration from Austrians circle and I affectionately see you both through them psychologically rather physiologically
