Hi everyone, I apologise in advance in if I have posted in the wrong thread.

I am trying to perform a t test here where I am using the AssessMark against the SuprtScore, QualScore, SatisfScore and SysBen columns.

As I am using excel to perform the computation, I am not so sure if I am doing it right for I am doing the following:

- Select AssessMark + SuprtScore column
- Using the T Test formula in excel but under the type, there is the tails and type that I need to define in which I am unsure of which
- Formula in Excel is: T.Test(range1, range2, tails, type)

1 = paired test

2 = two sample equal variance test

3 = two sample unequal variance test

- Formula in Excel is: T.Test(range1, range2, tails, type)
- If I input in the different tails/types, I am also getting different results.
