# Contingency Coefficient

*The higher C, the stronger the relationship between the variables.*

![C = square root of χ² divided by (χ² + n)](/principles-of-survey-research/media/formel_c.png)

The higher C , the stronger the relationship between the variables.

Values **> 0.30** are considered substantial.

Although C values have an upper limit of 1, they cannot actually reach this limit.

Problems:

- C is not standardized and depends on the table dimensions.
- C values from different studies cannot be compared with one another.

In our example:

![C = square root of 3.333 divided by (3.333 + 30) = 0.316](/principles-of-survey-research/media/formel_c_bsp.png)

The relationship is **not particularly strong.**
