The final assignment includes two parts: The problem below and narratives or written explanation/interpretation of the scenario and the test results, including statistical and practical outcomes.

Participants with an intense fear of snakes received one of four treatments. Some worked with a model who handled a four-foot king snake and encouraged others to imitate her. Others watched a film of adults and children who enjoyed progressively closer contact with a king snake. A third group received desensitization therapy, and a fourth group received no treatment, serving as a control group. The next slide shows the number of times each participant approached a king snake after treatment.

• Was there a difference in effectiveness of the treatments?
• Which treatment was more successful?
• How did the control group compare to the others?
• Here's a hint: you can use ANOVA and t-tests to answer these questions.
