Standard 91265 is worth 3 credits and is about the design of statistical experiments, collection of results and interpretation of those results. We will be carrying out this topic in conjunction with the Level 2 Psychology class in order to provide context to our experiments (and will therefore also be completing AS91846, Conduct psychological research with guidance, worth another 4 credits).
