DQ 2 :Research a health concern that impacts a population with which you are familiar
Three questions, and the middle one is not about reporting statistics. Biostatistics shapes what you can ask, and the phrase population as your patient is a translational nursing concept the course expects you to use deliberately.

Biostatistics shapes the question, not just the results
The instruction to include the population and the health concern is doing more work than it looks. A post that says obesity in my community has not named a population; a post that says adults over sixty-five with type 2 diabetes served by one federally qualified health centre in a specified county has. Everything else follows from that precision, because a defined population is what makes a rate calculable and therefore what makes the biostatistics question answerable at all. Choose something you can actually find data on, and check that data exists before committing, since the difference between a concern you can quantify and one you can only assert is the difference between this post working and not. County health department profiles, BRFSS tables and Healthy People objective data are the usual places that question gets settled quickly, and it is worth settling before you write a word of the post.
The second question is where most posts go wrong, because they describe statistics rather than explaining influence. Biostatistics affects the research focus upstream: incidence and prevalence figures decide whether a problem is worth a study at all, effect size and expected event rate determine the sample you would need and therefore whether a question is feasible, the measure available constrains what outcome you can choose, and confounders visible in the data force the question to be narrowed. Then handle the third question in the course's own terms. Population as patient is a translational concept: it means shifting the unit of care from the individual to the aggregate, so assessment becomes surveillance, the plan becomes a programme or a policy, and evaluation becomes a change in a population-level rate rather than an individual outcome. Say what that shift changes about your accountability, because that is the part the course is really testing.
Likely learning objectives
- Define a population precisely enough to make a rate calculable.
- Explain how biostatistics constrains a research question before data are collected.
- Apply the population-as-patient concept as a shift in the unit of care.
- Choose a health concern for which population-level data actually exist.

Course-wide instructions that accompany this question
ADDITIONAL INSTRUCTIONS FOR THE CLASS Discussion Questions (DQ) Initial responses to the DQ should address all components of the questions asked, include a minimum of one scholarly source, and be at least 250 words. Successful responses are substantive (i.e., add something new to the discussion, engage others in the discussion, well-developed idea) and include at least one scholarly source. One or two sentence responses, simple statements of agreement or “good post,” and responses that are off-topic will not count as substantive. Substantive responses should be at least 150 words. I encourage you to incorporate the readings from the week (as applicable) into your responses. Weekly Participation Your initial responses to the mandatory DQ do not count toward participation and are graded separately. In addition to the DQ responses, you must post at least one reply to peers (or me) on three separate days, for a total of three replies. Participation posts do not require a scholarly source/citation (unless you cite someone else’s work). Part of your weekly participation includes viewing the weekly announcement and attesting to watching it in the comments. These announcements are made to ensure you understand everything that is due during the week. APA Format and Writing Quality Familiarize yourself with APA format and practice using it correctly. It is used for most writing assignments for your degree. Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for APA paper templates, citation examples, tips, etc. Points will be deducted for poor use of APA format or absence of APA format (if required). Cite all sources of information! When in doubt, cite the source. Paraphrasing also requires a citation. I highly recommend using the APA Publication Manual, 6th edition. Use of Direct Quotes I discourage overutilization of direct quotes in DQs and assignments at the Masters’ level and deduct points accordingly. As Masters’ level students, it is important that you be able to critically analyze and interpret information from journal articles and other resources. Simply restating someone else’s words does not demonstrate an understanding of the content or critical analysis of the content. It is best to paraphrase content and cite your source. LopesWrite Policy For assignments that need to be submitted to LopesWrite, please be sure you have received your report and Similarity Index (SI) percentage BEFORE you do a “final submit” to me. Once you have received your report, please review it. This report will show you grammatical, punctuation, and spelling errors that can easily be fixed. Take the extra few minutes to review instead of getting counted off for these mistakes. Review your similarities. Did you forget to cite something? Did you not paraphrase well enough? Is your paper made up of someone else’s thoughts more than your own? Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for tips on improving your paper and SI score. Late Policy The university’s policy on late assignments is 10% penalty PER DAY LATE. This also applies to late DQ replies. Please communicate with me if you anticipate having to submit an assignment late. I am happy to be flexible, with advance notice. We may be able to work out an extension based on extenuating circumstances. If you do not communicate with me before submitting an assignment late, the GCU late policy will be in effect. I do not accept assignments that are two or more weeks late unless we have worked out an extension. As per policy, no assignments are accepted after the last day of class. Any assignment submitted after midnight on the last day of class will not be accepted for grading. Communication Communication is so very important. There are multiple ways to communicate with me: Questions to Instructor Forum: This is a great place to ask course content or assignment questions. If you have a question, there is a good chance one of your peers does as well. This is a public forum for the class. Individual Forum: This is a private forum to ask me questions or send me messages. This will be checked at least once every 24 hours.

Common mistakes
- Naming a health concern without bounding the population.
- Describing what biostatistics is instead of how it shapes the focus.
- Treating population as patient as a metaphor rather than a change in unit of care.
- Choosing a concern with no available population-level data.
- Evaluating success with an individual outcome rather than a rate.
Submission checklist
- Could someone calculate a rate from your population definition?
- Have you named the specific measure for your health concern?
- Does the biostatistics answer explain influence rather than definition?
- Is the shift from individual to aggregate care stated explicitly?
- Are your figures sourced rather than estimated?
