The writer's setting and colleagues are composite; the sources cited are real.
Where I Started
Before this course I read statistics the way many nurses do, looking for the p-value and the word "significant," then translating whatever percentage appeared into a headline. My project, an insulin discharge bundle on two composite Dubuque medical-surgical units, rested on a study whose adjusted odds ratio of 0.66 I had turned into "a third fewer readmissions." I did not know what an odds ratio was, how it differed from a risk ratio or why the interval mattered.
Moments That Changed My Reading
Three moments stand out. The first was rescaling a regression coefficient. A health literacy study reported a change in A1C of 0.02 per test point, which I first dismissed as trivial. Multiplying by the difference between two realistic patients, I found a gap of about 0.4 percentage points. A coefficient is only as small as its unit, and I now ask what one unit means before judging any slope.
The second was computing an odds ratio and a relative risk from the same illustrative table and finding 0.44 and 0.48. Because our outcome is not rare, the odds ratio makes the change look larger. Reporting it as a reduction in risk would have overstated our result, the same mistake I had made with the published study.
The third was reading the 2016 statement from the statisticians' professional association, which made clear that a p-value is silent on the size and the importance of an effect and that conclusions should not hinge on crossing .05 (Wasserstein & Lazar, 2016). I had been using "significant" to mean important, and so had most of my project team.
Statistical literacy, for me, turned out to be mostly the discipline of saying less, more precisely.
How I Will Use Statistics as a Leader
The course changed what I will put in front of decision makers. I will lead with differences in percentage points and with how many patients must be treated to prevent one event, which Laupacis and colleagues proposed precisely because they express benefit in terms people can weigh against effort and cost (Laupacis et al., 1988). Telling the nurse executive that about fourteen patients need the bundle to prevent one return is more honest and more useful than telling her the risk was halved.
I will also report uncertainty. A review of health research found that many papers using regression omit confidence intervals and few interpret the size of their estimates (Jones et al., 2025). If published authors struggle with this, a project team presenting to its own hospital is likely to as well, unless someone insists. I intend to be the person who asks for the interval.
Finally, I will name the design's limits next to the result. A before-and-after comparison on two units cannot prove the bundle caused a change, however small the p-value, and saying so at the start protects the project's credibility if the numbers move less than hoped.
Teaching Others
Statistical literacy is also a leadership responsibility toward colleagues. Our unit's monthly quality dashboard shows percentages with no denominators and arrows that change direction with every small fluctuation. I plan to propose two changes: show counts with every percentage, and use run charts with a median line so that staff can tell signal from noise. I have already shared the p-value statement with my project team and agreed with them on reporting language. We wrote a one-page guide: every rate with its count, every comparison with its interval, no use of the word significant without saying statistically, and a sentence on the design's limits in every summary. The guide sits in our shared folder and will be attached to each monthly report so that new team members learn the same habits.
What I Still Find Hard
Confidence intervals for small subgroups remain uncomfortable. Our Marshallese-speaking patients number fewer than ten a year, and any rate for them will have an interval too wide to mean much. I have learned not to test differences in such groups but to review each case, and I still need practice explaining to colleagues why a striking percentage in a small group is not yet evidence.
Conclusion
The sentence I would have said ten weeks ago was not a lie, but it claimed more than the evidence supported. Statistical literacy, as I now understand it, means reading a number for its scale, its uncertainty and its design, and presenting it so that decision makers know what it does and does not promise. That is the standard I will hold my own project to.

What the NU704 Unit 10 assignment asks for
The final unit of NU704 commonly asks students to reflect on their growth in statistical literacy and how they will use statistics as DNP-prepared leaders. Prompts typically expect specific moments from the course that changed the student's thinking, examples of how results will now be read and presented, attention to teaching others and an honest account of what remains difficult. Instructors reward reflections anchored in concrete numbers and decisions rather than general statements of improvement. Linking the reflection to the student's DNP project, where the same measures will be reported, is usually expected. A few sources can support claims about reporting practices or measures, such as the statisticians' statement on p-values or the case for the number needed to treat. The tone should be personal but professional, and every statistic mentioned should be stated correctly.
How the NU 704 Unit 10 example is put together
The reflection opens with the sentence the writer would no longer say and the study behind it. A section on the starting point describes reading for p-values and headlines. Three moments follow in turn: rescaling a regression coefficient, comparing an odds ratio with a risk ratio and reading the 2016 p-value statement, under a highlighted line about saying less more precisely, with a margin note on naming specific moments. In the leadership section the writer promises to open with percentage-point gaps and patients-per-event figures, after Laupacis and colleagues, to reporting intervals in light of Jones and colleagues, and to naming design limits. A teaching section proposes dashboard changes and a team guide, flagged by a second margin note. The writer then admits difficulty with tiny subgroups before a short conclusion restating the standard for their project.
Where the points sit in the NU704 Unit 10 rubric
Statistical literacy reflections are marked on specificity, accuracy, depth of change, application to leadership and honesty about limits. Specificity credit requires concrete moments and numbers from the course rather than general claims. Accuracy matters even in a reflection: any statistic mentioned should be correct. Depth rewards explanation of what the student misunderstood before and why the new understanding is better. Application to leadership is often weighted most, including how results will be presented to decision makers and how colleagues will be taught. Graders also credit plans that change systems, such as dashboards or reporting guides. Acknowledging a remaining difficulty shows maturity. Connection to the DNP project ties the reflection to the program. A clear structure, a professional voice and correct citations for any sources used complete the criteria in most sections.
Common NU704 Unit 10 mistakes, and how to avoid them
Reflections lose marks most often when they describe feeling more confident with statistics without showing a single number read differently. Another frequent weakness is restating course content as definitions instead of describing a change in practice. Some students make statistical errors in the reflection itself, which undermines the claim of growth. Others focus only on their own reading and ignore how they will present results or teach colleagues. Claiming to have mastered everything can seem less credible than naming one thing still hard. Begin by finding one sentence you wrote or said before the course about a study, and rewrite it the way you would now. The distance between the two versions is your reflection. Course notes and your project's key results are enough to draft a custom reflection.

NU704 Unit 10 questions, answered
What is statistical literacy?
The ability to read, question and use statistics correctly, including knowing what a number can and cannot support.
Should the final reflection include examples?
Yes. Specific moments from the course, and how they will change a decision, make the reflection convincing.
How long is the final reflection?
Often about two pages, depending on the section's instructions.
Where can I find a free NU704 Unit 10 sample paper?
You can read the full NU704 Unit 10 statistical literacy reflection on this page. It traces how three course moments changed the way a DNP student reads and presents statistics for an insulin discharge project.
What will the NU704 Unit 10 writer show decision makers first?
Differences in percentage points and the number of patients who must receive the bundle to prevent one return, with intervals, rather than relative reductions that can sound larger than they are.
