Hello,
I have a variable "firm's results" which is an ordinal scale and 5 variables for direct marketing, each of them in ordinal scale too.
I know that I can use Pearson if I want to know the correlation between all of them. But if I use the function in SPSS "Compute variable"for the direct marketing and have a values like: 14, 21 ..., can I look for correlation between the results and this values with Pearson again?
Thanks
You can use contingency co-efficient or lamda co-efficient. However if the scale is standardised and the sample size is large enough it will tend to normal distribution which can be checked by using p-p plots. Therefore, Pearson's correlation can also be used.
While Pearson correlation can be helpful in obtaining your result, you can also use Spearman correlation to measure the degree of association for your ordinal variables.
