This can be a challenging assignment, but it is key to making use of understanding causality in research methods.   Please complete this assignment before the end of the semester.  Please see the attached file for instructions.   There is a link to a research article. 

Understanding causation and research design is very critical skill in the study of Research 
Methods. This assignment will test your ability to recognize types of research design and 
determine if enough evidence is present to establish causation. Please locate and read the following research article:
