Purpose:
This assessment evaluates your ability to manage, analyse, and graph data using R in a reproducible and concise format. You will demonstrate practical data handling, statistical reasoning, and graphical representation skills using R code aligned with course modules.
Scenario: You as a Research Assistant
You are working as a research assistant on a fictional study evaluating the effectiveness of various exposure therapies combined with CBT (Cognitive Behavioural Therapy) in treating anxiety disorders. Your task is to complete data tidying and initial analysis in R.
You will use a dataset and answer a series of short-answer questions, including writing R code to support your answers.
