Discussion 5
The writing involves the following five parts:
- Introduction (what is the hypothesis you want to test; what is the population data you have in mind)
- data collection (what your sample data is and from where you collect them; on what basis you are convinced the sample is random)
- data summary and visualization (the basic summary statistics of your data and a visualization of the main feature of the data)
- hypothesis testing (a statistical statement of the hypothesis you want to test and the test statistics that you have computed)
- conclusion (what you can conclude concerning your hypothesis based on your test statistics)
You can choose your favorite statistical software to conduct the project. Write a 1.5-page single spaced memo of the data project detailing the above four parts and to submit the data file along with the memo.
Examples topics:
- Has vaccination made differences in inflation rates across the states in the U.S. (or the countries in the world)?
- Has the ongoing US-China antagonism affected the bilateral trades between these two countries?
- Is the same kind of bagels priced higher in Walmart than in Costco?
