What Statistical Test do I use (SPSS)

Question

I want to work out if the answer that two different programs produces are within an acceptable limit.

Do I do a correlation or an ANOVA

Answer 1

Hello,

<<... the answer that two different programs produces... >> needs to be better defined: what sort of answers? quantitative? qualitative? discrete? continuous?

ANOVA is a test for multiple populations > 2, so that won't be appropriate. Perhaps a 2-sample t-test or z-test or the non-parametric equivalents, depending *on the type of data being measured.*

Correlation is a possibility, but by no means the only relational test that might be applied.

Let me know. Regards,

Phil C.
