Use the Mean versus Median web app on the books website to investigate how the standard deviation
Question:
Use the Mean versus Median web app on the book’s website to investigate how the standard deviation changes as the data change. When you start the app, you have a blank graph. Under “Options”, you can request to show the standard deviation of the points you create by clicking in the graph.
a. Create 3 observations (by clicking in the graph) that have a mean of about 50 and a standard deviation of about 20. (Clicking on an existing point deletes it.)
b. Create 3 observations (click Refresh to clear the previous points) that have a mean of about 50 and a standard deviation of about 40.
c. Placing 4 values between 0 and 100, what is the largest standard deviation you can get? What are the values that have that standard deviation?
