Survey research and design in psychology/Tutorials/Correlation/Instructor notes

General advice to instructors

 * 1) Point out the practice correlation quiz
 * 2) Explain the general steps in conducting a correlational analysis (5 mins)
 * 3) Go over each cell of this table which shows (10 mins): types of correlation in relation to the level of measurement
 * 4) Demonstrate and assist students to conduct the types of correlation exercises (65 mins)
 * 5) Nominal by nominal
 * 6) Gender and God - do this step by step
 * 7) Smoking and Story - run via copied syntax and interpret output
 * 8) Demonstrate Correlation explore and Correlation guess. Challenge students to get 50% (very difficult). (10 mins)
 * 9) Note that one of the plots doesn't display on Correlation guess?
 * 10) Demonstrate and allow class to explore effects of outliers. (10 mins)
 * 11) An alternative is to conduct this as a whiteboard exercise (works well esp. if Java isn't working or time is tight)
 * 12) Demonstrate correlations and non-linear relations (5 mins). If time allows (generally not), set the task as a problem - to draw scatterplots and work out the correlations for each nominated pair and then to explain what is going on (10 mins).
