Can you correlate 2 Likert scales when the question for each one was different?
I have 1 question which asks how concerned someone is about pollution. They rank this on a Likert Scale of 1-5 where 1 is most concerned and 5 not at all.
Then my other question asks whether people intend to take any extra measures to reduce their own pollution in future, again on a scale of 1-5 but where 1 is very likely down to 5 not at all.
Can I run a correlation test on these two questions? Naturally I would expect the more concerned one is, the greater their intention to act. Obviously both scales are 1-5 but as the meaning behind what the number means is slightly different (I.e in Q1, 1= Most Concerned and in Q2, 1= Very Likely), can they still be correlated?
