Learning aim C For Distinction standard , learners will evaluate the outcomes and produce accurate,
valid and relevant judgements from the analysis of the effectively cleansed and
formatted data set. They will formulate a clear, specific, well-defined question to identify
what they want to know. Learners will select methods to generate valid, accurate and
relevant information. The analysis must include appropriate and accurate presentation
of data, calculations of central measures, dispersion and probability functions,
comparison of data sets and regression.
Learners’ presentation will be fit for two different audiences and a purpose to meet the
needs of an organisation. For example, they will clearly define the purpose of the
analysis and the intended audiences.
Overall, the evidence will be easily understood by a third party with a mathematical
background. There will be correct use of mathematical terminology and application of
relevant units. Learners will work to specified numerical accuracy, as determined by the
assessor, or that is appropriate in order for solving their chosen problems, through the
use of appropriate significant figures or decimal places. Small and large numerical values
will be correctly presented in an appropriate format, i.e. mathematical notation or
standard form.
For Merit standard , learners will prepare effectively a large raw data set so that the
analysis can be carried out to meet the needs of an organisation, for example by
removing the vast majority of the unwanted data and formatting the units, such as
currency or percentages, consistently. They will formulate a well-defined question to
identify what they want to know.
Learners will use industry standard software to analyse the data set by applying routine
and non-routine statistical, probability and mathematical operations accurately. For
example, they will present data, calculate central measures, dispersion and probability
functions, compare data sets and use regression techniques.
Learners will present concise conclusions and recommendations from the accurate
analysis of the data set which are fit for two different audiences and a purpose to meet
the needs of an organisation. For example, the audience for a presentation could be a
technical management meeting, and the other a shareholders’ report.
Overall, the numerical work will be to an appropriate degree of accuracy, as specified
by the assessor, or appropriate for the chosen problem being solved, and the methods
selected will be used correctly. Solutions will be logically structured and the correct
mathematical terminology and relevant units will be used. There may be a limited
number of minor errors or omissions in non-routine operations. For example, when
evaluating a data set, learners may determine the mean and standard deviation for a
sample and find a degree of correlation between samples, but not draw conclusions
from the values.
