Module overview
This module provides an introduction to the use of statistical methods for the analysis of quantitative data and their application in public health. This will include descriptive statistics and basic inferential statistics. The emphasis will be on the practical application of statistical methods and the interpretation of results using the statistical software SPSS. In addition to teaching you when and how to apply which quantitative analytical techniques when carrying out research or evaluating a programme, it will enable you to interpret your own results and those reported by others.

Assessment
Assessment strategy
The assessment includes both formative and summative elements. The formative assessments are SPSS exercises that are self-directed. There are two summative assessments: a data analysis report and an on-line multiple choice (MCQ) quiz.
The pass mark for the summative written data analysis report and the module is 50%. You must also pass the online MCQ quiz by achieving a mark of 90% or above. If you fail the MCQ quiz you are allowed to take it again until you pass within the specified time period. If you fail the module, you will have the opportunity to submit work at the next referral (re-sit) opportunity. On passing your referral, your final module mark will be capped at 50%.
Formative
This is how we’ll give you feedback as you are learning. It is not a formal test or exam.
