Homework #2 APPM 4570/5570, Statistical Methods, Fall 2017 Due in class on Friday February 2, 2018 . Instructions for “theoretical” questions: Answer all of the following questions. The theoretical problems should be neatly num- bered, written out, and solved. Please do not turn in messy work. Working in small groups is allowed, but it is important that you make an effort to master the material and hand in your own work. Note that you are also required to turn in the computational portion of this assignment. It is on Canvas, under the name hwk2_Sp18_appm4570-computational.ipynb. Theoretical Questions 1. In class, we learned about three measures of center: the arithmetic mean, the median, and the mode. This question will explore some other measures of center. (a) The trimmed mean is the arithmetic mean after the lowest x % and highest x % have been removed. i. Describe one advantage and one disadvantage to using the trimmed mean. ii. Is there another name for the trimmed mean when x = 50?

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
