Strength of relationship

Strength of relationship

The crudest and simplest method to measure the strength of the relationship for a 2x2-cell crosstab:

The method measures the change in percentage of the categories of the dependent variable in accordance with the changes of the independent variable.

In the above example:

  • It holds for all the 3 categories of financial status that there is no difference between medical condition – yes and medical condition – no.

  • On the other hand, in the table showing the actual distribution, there’s 2% difference according to financial status. It’s a very weak relationship considering that the maximum difference would be 100%.
