identify areas for improvement.

**Practice for Future Exams:** Understanding mark schemes helps students learn

how to structure their answers to maximize marks.

Breaking Down the S1 Exam: What to Expect

Before delving further into the unoﬃcial mark scheme, it’s useful to understand the

typical structure and content of the S1 exam.

Core Topics Covered in S1

The S1 Statistics module usually covers:

**Data Presentation and Interpretation:** Histograms, cumulative frequency graphs,

and box plots.

**Probability:** Basic probability concepts, including independent and mutually

exclusive events.

**Statistical Distributions:** Binomial and Poisson distributions.

**Measures of Central Tendency and Spread:** Mean, median, mode, variance, and

standard deviation.

**Hypothesis Testing:** Basic introduction to signiﬁcance testing and interpreting

results.

Understanding these topics is crucial because the mark scheme evaluates not only the

correct ﬁnal answers but also the approach and method used.

Exam Technique and Marking Criteria

The mark scheme for S1 emphasizes certain exam techniques:

**Showing Working Clearly:** Partial marks are often awarded for correct methods

even if the ﬁnal answer is wrong.

**Using Correct Notation:** Proper statistical notation is important to demonstrate

understanding.
