You can find bi variate correlation using SPSS software

Hi!

If you want to perform correlations between two variables (bivariate correlations), first you must pay attention to the kind of variables you want to correlate. Also is important the sample size (you said it's a small size):

a) If both variables are qualitative, you have to calculate chi square (in SPSS you can find it in Analize->descriptive statistics->crosstabs in Statistics button). Also you have Cramer's coefficient and others that work like this correlation coeficient, but the most used is chi square.

b) If both variables are in an ordinal scale, you have to calculate Spearman's correlation, but it depends on the number of levels, sometimes with chi-square test you solve the problem.

c) If both variables are quantitative, and your sample size is small (like you said), you must use Spearman's correlation coeficient, it works like Pearson's correlation when the sample size is small. (in SPSS you can find it in Analize->correlate->bivariate).

I hope this helps. Good luck with your research!

Best regards from Madrid

I agree with Madrid but the problem is that you have to know the statistical tool very well. Correlation analysis is just the best statistical tool. Good luck.

Gupta- i have forgotten but something like Whitney u, google also
