statistical methods to:
Analyse the data in accordance with the objectives of the study/program
appreciate the problem of sampling variation and the role of statistical methods in quantifying this by setting confidence
intervals and testing hypotheses;
select and use appropriate statistical methods for the analysis of small to medium sized datasets;
