Hi!
A research study involves measuring the math ability of three groups.
The first group is made up of non-Mexicans, born in the US and educated in the US.
The second group is made of of Mexicans, born in Mexico but educated in the US.
The third group is made up of Mexicans, born in Mexico and educated in Mexico.
Clearly, the dependent variable is math ability.
What is(are) the independent variable(s)?
