Breaking Down the Key Topics Covered in the June 2013 S2 Exam

The S2 exam typically covers several core statistical concepts, and the June 2013 paper

was no exception. The mark scheme provides solutions and marking comments for each

question, often highlighting the precise statistical techniques required.

Probability Distributions and Expectation

A significant portion of the paper tested knowledge of discrete and continuous probability

distributions. Questions involved calculating probabilities from binomial and normal

distributions, finding expected values, and using variance and standard deviation

formulae.

The mark scheme shows that partial credit is often given if students correctly identify

distributions or apply the right formulas but make calculation errors. This underscores the

importance of demonstrating a clear method.

Hypothesis Testing

Hypothesis testing is a fundamental topic in S2, and the June 2013 exam included

questions where students had to:

State appropriate null and alternative hypotheses.

1.

Calculate test statistics using given data.

2.

Make conclusions based on significance levels.

3.

The mark scheme emphasizes the need for clear statements about hypotheses and

correct interpretation of results. Marks are often lost when students skip these

explanations or misstate the significance level.

Regression and Correlation

Another area covered was regression analysis, including calculating regression lines and

interpreting correlation coefficients. The mark scheme rewards accuracy in calculations

but also values the interpretation of the results in context, such as explaining what a

correlation coefficient implies about the relationship between variables.
