What is the Purpose of your Study?


It is not worthwhile to go around the world to count the cats in Zanzibar (Maxwell 2005, citing Thoreau)

It is important to be clear about the reason why you are undertaking your study. An unclear purpose will result in a muddied up process, and therefore, results that may not be either credible or valid. The purpose statement is the central controlling idea in a study (Creswell, 2009, p. 111).

Maxwell (2005) “Qualitative Research Design” recommends that researchers write regularly and systematically about their research for the researchers own consumption, as well as for discussion with others. In his very helpful chapter 2, he discusses goals of research leading with the following question: Why are you doing this study?

The point is that you need to be clear on the purpose of your study, and that purpose has to lead to a question/questions whose answers are worth knowing. Clear goals serve as a guide for your study= goal here includes desires, motives and purposes, whatever is leading you to want to engage in your study.

Maxwell reminds us that goals a) help to guide your other design decisions to ensure that your study is worth doing, and b) they are essential to justifying your study.  It is likely that you have personal, practical and intellectual goals for you study. Personal goals motivate you to engage in the study but may not be of much value to others (e.g. need to advance your career, desire to change a situation). Often, personal goals influence your choice of dissertation topic, and are likely to impact your motivation (and persistence) through the dissertation process. More often than not, personal goals remain unstated – however, it is helpful to be clear on what your own personal goals are even if you will not discuss them in your study. Off course if you engage in qualitative, there is room to indicate the personal goals that are impacting your choices. For example, one of my mentees chose to study successful African immigrant faculty in US institutions, one because she is an African immigrant, and two, because as someone who desires to enter the professorial ranks, she is interested in learning how they ‘made it’. Another chose to study long term health care because this was his industry for many years as owner of nursing homes, and he consults to nursing homes today – thus his study would help to improve his consulting work. Being clear about your personal goals also enables you to be reflective of your subjectivities – it helps you beware of looking only for the answers that fit your presuppositions.

Practical and intellectual/scholarly goals are important to you as well as to other people. Practical goals focus on accomplishing something, meeting a need, changing a situation, achieving a particular objective; intellectual goals focus on understanding something, often filling a gap that other research has not adequately addressed. The second student (now a newly minted PhD) mentioned above, aimed at improving his own consulting practice by gaining a better understanding of leadership praxis within the long term health care industry. His study was endorsed by one of the industry professional associations in recognition of its practical utility.

Generally, the intellectual/scholarly goal of your study is framed in terms of ‘purpose statement’. This begins with a sentence such as:

The purpose of this study is to…(a verb here, such as evaluate, explore, explain, describe, determine, examine, etc. You then expand on that purpose in several sentences/a paragraph. 

Your practical goal is framed in terms of the “Significance of the Study” where you talk about the relevance or practical utility of your study to practitioners – teachers, administrators, managers, pastors – the ‘second’ audience of your study. Your significance section also discusses further your scholarly goal by discussing how your study will expand our understanding of a particular area of study. In qualitative studies, you would need to discuss your personal goals, either in chapter 1 or chapter 3 (Introduction, or Methods) with a sub-heading such as ‘role of the researcher’, ‘researcher presuppositions’, ‘researchers predilections’, ‘how I came to this study area’…etc.

Both Maxwell (2005, chapter 2) and Creswell (2009, chapter 6) offer helpful templates for constructing your purpose statement. Maxwell offers templates/exercises for constructing a purpose statement for a qualitative study. Creswell offers templates for qualitative, quantitative and mixed methods designs. Both provide excellent examples of well crafted purpose statements.

  1. I intend to cut and paste this and answer all of these questions and follow this recipe. Well done and thank you. Now I just have to find the time. I have often thought that we should be able to substitute some of our course committments with our PhD Dissertation Applicaton committments.... no such luck huh?

    1. Eventually, coursework gets completed, and then you can focus on the dissertation...but still, the time demands and commitments will continue with work, elder-care, child-care. Very few people get to focus on just the dissertation with no other demands on their time; at least it seems that way in this day and age when most doctoral students/candidates are middle aged or older when they start this journey. The two texts are written in a way that you can easily DIY without need for too much guidance (other than off course ensuring you are getting feedback from your chair). Get Creswell now if you don't already own it.
