I have time series survey data, with different respondents at each interval with an attitudinal DV (say, happiness). I'd like to compare two groups of respondents (say, males and females).
1) What is the best test to compare these two groups to determine whether they are significantly different overall from one another (i.e., average happiness)?
2) Also, what's the best test to compare the trends seen in the two groups (e.g., males and females trending in different directions in terms of their happiness over time)?
Thanks!
