we need to load this app the Mean Versus Median Applet Or, from StatCrunch, select Applets &gt; Mean/SD vs. Median/IQR. Select the "Randomly generated" radio button. Verify the Mean and Median boxes are checked and click Compute!. 1. Click "Reset" at the top of the applet. a. Create a data set of ten observations such that the mean and median are both roughly equal to

2. b. Click "Add point" and add a new observation at 9. How does this new value affect the mean? The median? 2. a. Remove the single value near 9 by clicking on the point and dragging it off the number line. b. Click "Add point" and add a single observation at 24. How does this new value affect the mean? The median?

3. Click "Reset" at the top of the applet. a. Add a point at 0. Add a second point at 50. Remove these points by dragging them off the screen. (This is done to create a number line from 0 to 50). b. Create a symmetric data set of six observations such that the mean and median are roughly 40. c. Add a single observation at 35. How does this new value affect the mean? The median?

d. Grab this new point at 35 and drag it toward 0. What happens to the value of the mean? What happens to the value of the median? In this activity you will use an applet to investigate the mean and median as measures of center and explore the resistance of these measures.

r 4. Click "Reset" at the top of the applet. a. Add a point at 0. Add a second point at 50. Remove these points by dragging them off the screen. b. Add about 25 to 30 points to create a symmetric dot plot such that the values of the mean and median are roughly 40. c. Add a single observation at 35. How does this new value affect the mean? The median?

d. Grab this new point at 35 and drag it toward 0. What happens to the value of the mean? What happens to the value of the median? 5.
what you have learned in this activity about the mean and median. include a discussion of the concept of resistance and the role sample size plays in resistance.

6. Click "Reset" at the top of the applet. a. Add a point at 0. Add a second point at 50. Remove these points by dragging them off the screen. b. Create a data set of at least ten observations such that the mean equ
