Topic 2: Two or more samples are often compared when we suspect that there are differences between the groupsfor example, are cancer rates higher in one town than another, or are test scores higher in one class than another? In your chosen field, when might you want to know the mean differences between two or more groups? Please describe the situation (what groups, what measurements) including how and why it would be used.

Topic 2 Example:

I decided to talk about the difference in deployment rates between the Army active duty and the Army Reserves. After doing some research, I came across a website that shows different tables of deployment research. The first chart talks about the proportion of deployed service members deploying multiple times, by a branch of service. As you can see on the chart with the link provided below, it does talk about all branches as a whole but I am just solely focusing on the US Army. For regular Active duty Army, the total amount deployed was 287,938 (47.3%). In the reserves, only 57,201 (32.9%) were deployed. In the second table, the mean number of deployments for the active duty army is 1.76 and the Reserves is 1.45.

I think this is pretty significant being an active-duty soldier as the percentage is greatly different. Looking at all the statistics of other branches the Army is truly the highest percentage of all.
