You can also describe a relationship by telling whether it is

like a function or

only predictable with some extent of certainty

Example:

(These data are fictitious but they were generated on the basis of those presented above)

if the relationship is deterministic, the strength of the relationship (the steepness) and the value of the independent variable yields the exact value of the dependent variable

if it’s stochastic, we can only give its most probable value

deterministic relationships are also called function-like

Which type is more typical in social science?

**Summary**

we can describe the relationship between two high measurement level variables

but we can’t give its exact strength and direction

so how can we draw the line defined by the values?

by describing the relationship between two high measurement level variables using one single number
