Nomothetic Causal Explanations
Nomothetic causal explanations require a type of math to be proven. They use variables and look for changes in those variables. Basically:
IV (Independent Variable) changes the DV (Dependent Variable).
Independent Variable: The thing that is being manipulated or observed
Dependent Variable: The thing that is changed based on the manipulation or observation
The hypothesis describes the relationship of the these variables and what we think is going to have happen.
To be able to be causal… must…
Covariation: “the degree to which two variables vary together”
Plausibility: in order to make the claim that one event, behavior, or belief causes another, the claim has to make sense
Temporality: “whatever cause you identify must happen before the effect”
Nonspuriousness: Spurious- “an association between two variables appears to be causal but can in fact be explained by some third variable”
Control Variables: “potential ‘third variables’ effects are controlled for mathematically in the data analysis process to highlight the relationship between the independent and dependent variable”
