Which statement is true about the relationship between the independent (X) and dependent (Y) variables in a quantitative research question? Select all that apply. One, some, or all responses may be correct. Correlational research attempts to look at the relationship between X and Y. Comparative research looks at whether there is a relationship between Y and people who have the X characteristic compared to those that do not have the X characteristic. Experimental research looks at whether Y changes based on where Group A received X and Group B who didn't receive X. There is no restriction to the number of variables (X or Y) that can be used in a study. The relationship between X and Y is always causal in nature
