Question 1 1 pts It is important to understand that when studying two variables, each variable has a role to play. That is, a variable may either be a response variable, also known as the dependent variable, or outcome variable, or it could be the explanatory variable, also known as the independent variable or predictor variable. Independent 4 [Choose] response explanatory predictor dependent [ Choose ] " outcome explanatory V Question 2 1 pts At this point, I'm going to be asking you to impose a causal model on your research question. To do this, you'll need to designate which of your variables is the explanatory variable and which is the response variable. Note that we can only impose a causal model, rather than actually test for causation, because we're working with what's known as observational data. In other words, the data sets that we're using are based on studies where the sample is simply observed, rather than being manipulated or inuenced in any way, as it would be in an experiment. Even though we won't be able to be certain that the association we're testing is causal, for the purposes of exploring our question, it remains important to determine the role that each variable will play in our model. observational data I J [ Choose ] l we can only impose a causal model we can actually test for causation experiment [ Choose 1 VI D Question 3 1 pts Recall that our basic research question is focused upon whether or not two variables are associated with one another.
