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.
