Which measure of association do I use?

In order to choose a measure of association, you take into account the (a)symmetry of the association and the level of measurement. You can use this table to determine which measure of association is appropriate for your variables and association.

When you do not know if there is a causal relationship between your two variables, you are testing a symmetrical relationship.

When you expect one variable (independent) to affect the other (dependent), you are testing an asymmetrical relationship.


**Note: ‘beide variabelen’ is Dutch for ‘both variables’
