Size:  48.8 KBHey everyone, I'm trying to work out how to do a T test for the data collected for my coursework, but I'm struggling on exactly what I need to do and what sort of figures I should be getting as a result.

    I have two sets of results, one is a control. I have uploaded screenshots of the first 5 sets of data in each of the tables (they both have 12 in but I don't want to upload the full tables for various reasons).

    The tables show the diastolic and systolic blood pressure of volunteers before and after consumption of liquorice (or a placebo sweet) with the difference in blood pressures in the far right hand columns (before consumption on day one compared with after consumption on day 10).

    What data do I need for a T test? I was planning to use this site http://www.mathportal.org/calculator...calculator.php

    Any help is greatly appreciated.

    Edit: the comparison is meant to just be on systolic blood pressure, not diastolic. I have just included that for the sake of being able to see the difference and as an evaluation point.
