Let’s be honest: for many students in health sciences, Epidemiology and Biostatistics is the “Final Boss.” It’s the moment where the comfort of clinical symptoms meets the cold, hard world of math. One minute you’re discussing disease outbreaks, and the next, you’re staring at a forest plot or trying to figure out if your $p$-value is significant enough to change medical history.

But here is the truth: Epidemiology isn’t just about formulas; it’s about storytelling with data. And the best way to learn that story is to see how it’s been told in previous exams. To help you move from “statistically confused” to “statistically confident,” we’ve put together a specialized Epidemiology and Biostatistics Past Paper Vault for you to download.
Before you grab the PDFs, let’s test your logic with some of the most common questions that trip students up during finals.
Epidemiology & Biostatistics Q&A: Your Revision Sprint
1. What is the difference between Incidence and Prevalence?
This is the “Question One” of almost every paper.
-
Incidence: Refers to new cases of a disease in a population over a specific time. Think of it as water flowing into a bathtub.
-
Prevalence: Refers to all current cases (new and old) at a specific point in time. This is the total water already in the tub.
-
The Exam Trick: If a disease has a high incidence but people recover (or die) very quickly, the prevalence will remain low.
2. How do you choose between a Case-Control and a Cohort study?
This is where the marks are won or lost in the “Study Design” section.
-
Case-Control: You start with the outcome (people who already have the disease) and look backward in time to find the exposure. It’s great for rare diseases.
-
Cohort Study: You start with the exposure (people who smoke vs. those who don’t) and follow them forward in time to see who gets the disease. It’s the gold standard for proving a “risk,” but it’s expensive and slow.
3. What does a 95% Confidence Interval (CI) actually tell you?
Students often think it means “95% of the data is here.” Wrong! A 95% CI tells you that if you repeated the study 100 times, the “true” population mean would fall within that range 95 times.
-
Pro-Tip: In an exam, if the Confidence Interval for an Odds Ratio or Relative Risk includes the number 1.0, the result is not statistically significant.
4. Can you explain Sensitivity vs. Specificity in a screening test?
-
Sensitivity: The “True Positive” rate. It’s the test’s ability to correctly identify those with the disease. (Sensitivity = Teenagers who are sick).
-
Specificity: The “True Negative” rate. It’s the test’s ability to correctly identify those without the disease. (Specificity = People who are healthy).
Why Downloading These Past Papers is Vital
In Biostatistics, reading the textbook is only 20% of the battle. The other 80% is knowing which formula to use and when. By practicing with our downloadable papers, you will:
-
Decode the Formulas: Get comfortable with the Standard Deviation, Standard Error, and Chi-Square tests before you have to do them for real.
-
Interpret Graphs: Practice reading Kaplan-Meier survival curves and Receiver Operating Characteristic (ROC) curves.
-
Master the “Critical Appraisal”: Many papers give you a snippet of a fake study and ask you to find the “bias.” Past papers teach you to spot Selection Bias and Confounding like a pro.
