5. is guided by the specific research problem, question or hypothesis
6. it accepts certain assumptions

Causation
-scientific explanations rest on the idea that events and conditions have causes
-a language of variables
-dependent variable (effect) is explained by the presence of the independent
variable (cause)
-in social science, a cause is not necessarily followed by an effect
-causation models in social science are often probabilistic
Finding causes in social science
-find reasons why observe something
-not enough to attribute cause to “choice”
-must explain why different choices are made
-example: education and prejudice
-can discover the factors and modify them
Correlation
-slopes and graphs
Variables
-we need to define our variables
-they comes from what we call concepts
-variables are concepts which share a special relationship within our theories
Independent Variables
Dependent variable
-the explaining variable (the cause)
The explained variable (effect)
The exogenous variable
The endogenous
