What are Advantages to Correlation study?
An advantage of using a correlational study is that it allows you to investigate variables that cannot be directly manipulated.
What are the Difference between endogenous and exogenous variables?
Endogenous variables are important in econometrics and economic modeling because they show whether a variable causes a particular effect. Economists employ causal modeling to explain outcomes (dependent variables) based on a variety of factors (independent variables), and to determine to which extent a result can be attributed to an endogenous or exogenous cause.
What does a straight line tells you on a line graph?
It tells you that the two variables in the graph change together at the same rate. There may or may not be a causal relationship between the tw variables: both could be related to a third variable which is not part of the graph.
Is correlational study qualitative or quantitative?
quantitative.
What is Causal Validity?
Causal validity is also referred to as internal validity. It refers to how well experiments are done and what we can infer from those results.
