I have to write a paper for quantitative research methods. I have no idea what subject and variables to use! I can write the paper myself once I get the subject. I have to formulate a theory about the correlation between measurable independent variables (causes) and one measurable dependent variable (the effect). I can't get past the Purpose Statement:In one paragraph, state the correlation and identify the primary independent variables.State the correlation as in the following:“The dependent variable _______ is determined by independent variables ________, _________, ________, and ________.”Identify and defend the “primary” independent variable, or the variable believed to have the strongest impact on the dependent variable:“The most important independent variable in this relationship is ________ because _________.”Only Government sources are allowed and I am totally blocked. Any suggestions would be appreciated.
