Notes for Session 6, Part A


Note 2

You will investigate the distinction between an observational study and an experimental study. Several examples are presented to illustrate the difference between these two types of studies. Group discussion should focus on how the nature of experimental studies allows us to make inferences about cause and effect. In contrast, an observational study can determine if there is a difference in measurements between two groups of individual objects but cannot conclusively attribute this difference to any particular factor.
