What factors should be used to gauge the quality of previous research?

Newton, Bower, and Williams (2004) outline the process of “devising and revising” a research question, be it descriptive, relational, or comparative. After reading their paper, write a three-page paper that addresses the following:

1. How do descriptive research questions differ from questions of relationship? From questions of comparison?

2. How should a researcher determine if prior research exists on the intended research topic?

3. What factors should be used to gauge the quality of previous research? Why are these important in making this assessment?

4. Should formulation of a research question precede or follow consultation with the scholarly literature? Please explain.

Assignment Expectations

You are expected to consult the scholarly literature in preparing your paper; you are also expected to incorporate relevant background readings.
Your paper should be written in your own words. This will enable me to assess your level of understanding.
In order to earn full credit, you must clearly show that you have read all required background materials.
Cite your references in the text of all papers and on the reference list at the end. For examples, look at the way the references are listed in the modules and on the background reading list.
Proofread your paper to be sure grammar and punctuation are correct and that each part of the assignment has been addressed clearly and completely.Your assignment will not be graded until you have submitted an Originality Report with a Similarity Index (SI) score <20% (excluding direct quotes, quoted assignment instructions, and references). Papers not meeting this requirement by the end of the session will receive a score of 0 (grade of F). Do keep in mind that papers with a lower SI score may be returned for revisions. For example, if one paragraph accounting for only 10% of a paper is cut and pasted, the paper could be returned for revision, despite the low SI score. Please use the report and your SI score as a guide to improve the originality of your work.
Length: 3 pages typed, double-spaced.
