Question: A student wonders if the Research Methods class he took actually improved his ability to cite and paraphrase sources. He had all of his writing

A student wonders if the Research Methods class he took actually improved his ability to cite and paraphrase sources. He had all of his writing assignments from the semester prior to taking research methods as well as his assignments from the semester during which he took research methods. He had a professor rate the citation and paraphrasing skill demonstrated in each assignment on a scale from 1 to 10. He gave the professor the work in a random order to avoid any potential biases, and then grouped them by semester and sequenced the ratings by due date:

1. What type of design is this?
2. Graph the results.
3. Is there evidence that the Research Methods class improved the student's citation and paraphrasing skills? Explain.
4. What are the limitations of this study?
5. Do you think the student should conduct an ABA, ABAB reversal design, or a multiple baseline- across-persons design? Explain.
