Do we discard the negative sign? Does it mean anything?

[@stikpet]

A + or - value occurs due to the t-value from the test. In turn this t-value is + or - based on the numerator in that calculation. This is usually average of before - average of after. This will be negative if the average of after is greater than the average of before.

Which version of SPSS is this?

[@stikpet]

I think it was version 27, should still work. For older versions it is more tricky kzbin.info/www/bejne/fWbKoXl3hrmeeMk
