IHP 525 is SNHU’s Biostatistics course. It centers on biostatistics for public health: descriptive statistics and distributions, estimation with confidence intervals, hypothesis tests including t-tests and chi-square, power and multiple comparisons, sensitivity, specificity and predictive values, regression and missing data, and responsible interpretation of p-values. Every module below opens a full sample paper or takes a free request for one; searches like "ihp 525 module 3", "IHP525 sample paper" and "IHP 525 milestone example" land on this page.
What IHP 525 is really about
IHP 525 is part of the SNHU MPH curriculum, and its rubrics reward correct calculation and sound interpretation in equal measure. Graders look for each statistic matched to the type of data, calculations shown step by step, confidence intervals reported alongside p-values, cautious interpretation that avoids treating nonsignificant results as proof of no effect and plain-language explanations that a program manager could follow.
Samples on this shelf follow a composite MPH analyst at the Bayview County health department evaluating a community blood pressure program that enrolled 240 adults through barbershops and churches and compared them with 260 similar clinic patients. Across the term, the analyst examines p-values, describes the data, frames the research question, runs t-tests and chi-square tests, plans power and handles multiple comparisons, evaluates a screening device, interprets regression results, explains uncertainty and writes the final report. The analyst, program and data are illustrative.
What IHP 525’s modules ask for
Across ten modules, IHP 525 typically asks for discussions of statistical reasoning, papers on descriptive statistics, hypothesis testing, diagnostic accuracy and communication of results, three milestones that frame a question, plan the analysis and report results, a final statistical report and a reflection.
Where students lose points in IHP 525
The most common IHP 525 deduction is a p-value treated as the whole answer: significant means important, nonsignificant means no effect. The second is a test mismatched to the data, such as a t-test on a yes-or-no outcome. Graders also mark down calculations without steps, results without confidence intervals, continuous variables needlessly split into categories and missing data ignored. The fix is to match tests to data, show every step, report estimates with intervals and interpret results in context.
The IHP 525 drawers
IHP 525 Module 1 Discussion example
An opening Discussion post from a health department analyst whose manager wanted to cancel a pilot program because its result had a p-value of 0.07. She uses the American Statistical Association's statement on p-values from Wasserstein and Lazar, Greenland and colleagues' guide to common misinterpretations and Sterne and Davey Smith's critique of significance testing to explain what the number means and what should inform the decision.

IHP 525 Module 2 Descriptive Statistics Paper example
A graduate paper describing baseline data from a composite county's community blood pressure program. It chooses summary statistics by variable type and distribution, calculates a standard error and confidence interval for mean systolic pressure as Gardner and Altman recommend, argues against splitting blood pressure into controlled and uncontrolled alone using Altman and Royston's analysis of the cost of dichotomizing and flags missing follow-up data using Sterne and colleagues' guidance on multiple imputation. Full sample paper, read it free.
IHP 525 Module 3 Milestone One example
A Milestone One framing of the statistical evaluation of a composite county's community blood pressure program. It states a primary research question and hypotheses, defines each variable by type and role, keeps the outcome continuous in line with Altman and Royston's warning about dichotomizing, commits to estimation with confidence intervals as Gardner and Altman urge and checks that planned regression models respect the events-per-variable guidance from Peduzzi and colleagues. Full sample paper, read it free.
IHP 525 Module 4 Hypothesis Testing Paper example
A graduate paper that works a two-sample t-test on change in systolic pressure and a chi-square test on blood pressure control for a composite county's program and comparison group, showing every step. It reports each result with a confidence interval as Gardner and Altman advise, checks interpretations against the misreadings Greenland and colleagues catalog and uses Altman and Bland's warning about absence of evidence to explain what a nonsignificant subgroup result does and does not show. Full sample paper, read it free.
IHP 525 Module 5 Milestone Two example
A Milestone Two statistical analysis plan for a composite county's blood pressure program evaluation. It calculates sample size and power for a 5 mm Hg difference, explains why the earlier 60-person pilot was underpowered using Button and colleagues' account of how small studies mislead, handles six secondary comparisons with the Bonferroni approach Bland and Altman describe and plans multiple imputation for missing follow-up following Sterne and colleagues. Full sample paper, read it free.
IHP 525 Module 6 Diagnostic Tests Paper example
A diagnostic accuracy paper that judges a home blood pressure monitoring routine against 24-hour ambulatory readings in 400 composite adults. It works out sensitivity, specificity and their confidence intervals, shows how predictive values collapse when the device moves from a high-risk clinic to the general county population and compares cutoffs on an ROC plot, drawing on the three diagnostic test notes by Altman and Bland. Full sample paper, read it free.
IHP 525 Module 7 Milestone Three example
A Milestone Three results section for the composite blood pressure evaluation. It reports an adjusted linear regression of six-month change, a logistic model for control with an events-per-variable check from Peduzzi and colleagues, imputed and complete-case estimates following Sterne and colleagues and effect sizes with intervals in the spirit of Gardner and Altman, while keeping pressure continuous as Altman and Royston advise. Full sample paper, read it free.
IHP 525 Module 8 Communication Paper example
A communication paper that turns the composite blood pressure evaluation into plain messages for a county board of health deciding on expansion. It draws on Spiegelhalter's review of risk and uncertainty communication, Gigerenzer and colleagues on counts out of 100 and absolute changes and Altman and Bland's warning that a missing significant result is not proof of no effect, applied to the women's subgroup. Full sample paper, read it free.
IHP 525 Module 9 Final Project example
A final statistical report bringing together the composite county's blood pressure evaluation, from design through recommendations. It is organized along the STROBE items von Elm and colleagues set for observational studies, reports estimates with intervals as Gardner and Altman urge, explains missing data handling after Sterne and colleagues and revisits the inconclusive pilot through Altman and Bland's note on absent evidence. Full sample paper, read it free.
IHP 525 Module 10 Journal example
A closing journal in which a county program analyst reflects on the term: how the pilot's p of 0.07 nearly ended a useful program, why small samples mislead, and why every analysis rests on choices that need to be written down first. It draws on Wasserstein and Lazar, Button and colleagues and Gardner and Altman. Full sample paper, read it free.

Using a IHP 525 sample the right way
Read an IHP 525 sample by checking three things: the test fits the data, every step of the calculation is shown and the interpretation reports an estimate with a confidence interval in plain words.

IHP 525 questions, answered
What does IHP 525 cover?
Biostatistics for public health: descriptive statistics, estimation, hypothesis testing, power, diagnostic accuracy, regression, missing data and interpreting and communicating results.
What does a p-value actually mean?
How compatible the data are with a specified model, such as no difference; it is not the probability that the hypothesis is true and says nothing about effect size.
What makes a strong IHP 525 paper?
Tests matched to data types, calculations shown step by step, estimates with confidence intervals and cautious, plain-language interpretation.
