Scatter diagrams and correlation
infoWhy this? Scatter diagrams reveal relationships between two variables and help us describe the direction and strength of association. Distinguishing correlation from causation is essential for evaluating claims about how one factor relates to another.
scheduleWhy now? Having described and compared distributions, we now investigate paired observations of two variables. Recognising patterns of association provides the foundation for the estimation methods and numerical measures of correlation that follow.
