Deterministic vs stochastic relationship

Deterministic vs stochastic relationship

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
