Hello, to study a relationship between categorical variables we can rely on the examination of the appropriate percentages. To summarize and measure the strength of a relationship, we can use Association coefficients.

An association coefficient or correlation coefficient is an index of how strong a relationship between two variables is; a value of 0 indicates no relationship, whereas a value of, normally, 1 represents the maximum (a few coefficients have a maximum lower than 1, some can exceed 1 in particular conditions). Coefficients meant for ordinal or higher levels of measurement are signed to indicate a positive or negative association (direction of the relationship).

There is a large number of association coefficients; they differ for two reasons:

Measurement level requirements: there are nominal coefficients, ordinal coefficients etc.

Statistical approach: There are several types based on different statistical ideas, for instance there is a family derived from the χ^2 statistic.

For more info see attached paper.

Good luck.!

Hi, check the package wildlifeDI (function Ca) in R.

Cheers

you can use SPSS it is very helpful and easier than Matlab
