Hello
I want to find r correlation between the same test but the different periods.
for example:
I scored tests in April and October and I need to know the correlation between these periods.
I find multivariate function in JMP but I need result in table not in graph.
I need receive 2 columns Name of test and Correlation for each test.
In excel I can use CORREL function, but didn't find something similar formula to do it.
