Dear All, Apart from using a regression analysis in SPSS/Minitab to find the correlation between 2 variables, are there any other correlation identifiers/tools around? Are there any differences of using Ms Excel to find the correlation between 2 variables as compared to using SPSS/Minitab? Anyway, it will subject to a certain degree of accuracy for any tools in my opinion! Thanks in advance.
