Sharpen your argument
A hypothetical study estimates a mean difference of 4 points with a 95% confidence interval from −1 to 9. What can you conclude? Choose the strongest starting point.
The estimate is 4 points, and the interval includes zero.
This does not prove that the true effect is zero. Discuss the range of effects compatible with the method and the study’s assumptions.
The weaker choice: Choosing a method is harder than pressing a software button. Identify the outcome type, the comparison and the assumptions before interpreting the result. watch this!

Is this course for you
Who tends to do well, and who tends to struggle
You will likely do well if
- Describe the research question, variables and sampling process first.
You may struggle if
- Choosing a method is harder than pressing a software button. Identify the outcome type, the comparison and the assumptions before interpreting the result.
- Write an interpretation with uncertainty and limitations, not only a p-value.

How to actually pass it
A weekly rhythm, two checklists, and the traps to avoid
The course rewards consistency over cramming, and practice over re-reading. Here is the loop that works, then what to have nailed before each exam.
The weekly loop
Before the mid-semester checklist
- Check the current source version and task brief.
- Explain the main concept without copying the wording.
Before the final heaviest topics
- Review your assumptions and evidence.
- Check the current submission and permitted-use rules.
The mistakes that cost marks
Skipping the assumptions. Choosing a method is harder than pressing a software button. Identify the outcome type, the comparison and the assumptions before interpreting the result.
Formula & concept sheet
The vocabulary and formulas you must own
- Confidence interval
- An interval produced by a procedure with a stated long-run coverage rate.
- Correlation
- A measure of association that alone does not establish causation.
- Sampling distribution
- The distribution of a statistic across repeated samples.
