AQA Certificate Level 3 Mathematical Studies₁₃₅₀

S4.1

understanding what is meant by the term ‘population’ in statistical terms

S4.2

developing ideas of sampling to include the concept of a simple random sample from a population

S5.1

knowing that the mean of a sample is called a ‘point estimate’ for the mean of the population

appreciating that accuracy is likely to be improved by increasing the sample size

S6.1

confidence intervals for the mean of a normally distributed population of known variance using $\frac{{\mathit{\sigma }}^{\mathsf{2}}}{\mathit{n}}$

confidence intervals will always be symmetrical

the confidence level required and the sample size will always be stated
