This is a student workbook that can supplement lessons on hypothesis tests for a population mean. I teach the stages of hypothesis testing using analogies to a criminal trial. My students like this comparison; they are more engaged and it helps them to see the relevance of the different stages. Once students are confident with the terminology, we create our own courtroom in the classroom and role-play the stages of hypothesis testing with students acting as the jury, prosecution, judge and defence.Contents of the workbook1.
