I am completing a statistics project having been given data for 30 years.

I have calculated the pairwise correlation coefficients between Infant Mortality Rate and 3 variables, I now need to test the statistical significance of each correlation coefficient. How do I do this?

Thanks

Hi,
Are you using the Pearson correlation?

Given the number of cases, you can work out the degrees of freedom (df=n-2). Then critical Pearson 'r' value for signficance at a particular alpha level (typically 0.05) can be found using a table of critical values such as this one:
