INFERENTIAL STATISTICS FOR DECISION MAKING
Week-9 Discussions, Reflections, and Questions
Please discuss, elaborate, and reflect on the following from chapter10. I have listed the important topics and some of them are questions.
Give examples and elaborate on the applications of the topic. After reading your textbook, I want you to have a good understanding of the fundamentals of each chapter and show it to me. Please don’t copy & paste from your textbook or some other online source. In other words, don’t plagiarize. You can read online material if it helps to understand the material, but you have to write your own sentences.
Chapter-10 topic Discussions and questions:
- Describe the following terms: treatments, experimental group, and control group. Give examples and applications.
- How do you create a paired-sample experiment? Discuss in detail and give examples.
- What does “Power” mean in an experiment?
- What factors impact the power of an experiment?
- The Smiths and McDonalds blame each other for Michael and Jane falling in love. On a test of propensity to fall in love, the mean of 6 members of the Smith family was 54 and the mean of 10 members of the McDonald family was 64. When a statistician compared the families’ scores with a ttest, to determine if one family was more at fault, a t value of 2.13 was obtained. As a statistician if you adopt an α level of .05 (two-tailed test), what should be your conclusion?
