The type is Numeric and the level of measurement has been correctly identified as Scale. Please try using the Friedman Test While you now know how to find correlation coefficient in each of the groups, but still we do not know if the difference in relationship between groups is significant. The decision rule therefore is: In the example above, zobs value of .206, that is between the boundaries, so we can conclude that there is a no statistically significant difference in the strength of the correlation between ATIB and SI for males and females.
