Test of Significance
Instructions:
Watch the video, Tests of Significance.
(Tests of Significance, 2013)
In the video, you observed the value of statistics in determining the authorship of a newly discovered poem. Consider the video and review your course readings on statistical significance, and then select a situation in your life or career where statistics could be used to answer questions. Examples could include authorship, quality of products, or health issues. After making a selection:
Describe the situation and the question(s) you would hope to answer using statistical tests.
Write a null hypothesis for your question(s).
Assume you conducted your statistical tests and were able to reject the null hypothesis. How would you interpret the results?
Discuss whether statistical significance would mean you should change the way you approach your situation. (For example, if a new drug on the market lowered blood pressure by 2 percent and this difference was found statistically significant, would it be worth using the new drug?)
Please be sure to validate your opinions and ideas with citations and references in APA format.
