Suppose that, as part of a research methods class, Bailey was asked to write a summary of a research paper on the effects of recruiting through social media on college enrollment rates. For the summary, identify the explanatory and the response variables.

Whether social media was used for recruiting is the explanatory variable, and college enrollment is the response variable.

Whether social media was used for recruiting is the response variable, and college enrollment is the explanatory variable.

Whether social media was used for recruiting and college enrollment are the explanatory variables.

Whether social media was used for recruiting and college enrollment are the response variables.

Answer: according to how the summary of the research should be, the variables are; "social media was used for recruiting is the explanatory variable, and college enrollment is the response variable".

Explanation: Variables are determining conditions of a result. In this research, we have two variables, one is an effect and the other is an outcome. From the research paper title, we can see effect of recruiting through social media to determine the out come of college enrollment rate.

In a research work, we study the effect and observe the outcome.

The research will try to explain the effect of social media been used for recruiting, and then the response of college enrollment. That means if we increase or reduce recruitment through social media how will college enrollment respond. This makes using social media for recruiting to be the explanatory variables and college enrollment to become the response variables.
