 '''Optional Extra-credit Project:'''  I give you the opportunity to complete an '''optional extra-credit''' project.  These projects can be a lot of work, but they can also be, for less extra credit, much less work.  Topics will be different for each person.  Your project must relate to statistics. Your project must involve effort that has an educational benefit to you.  There must be a component of the project that communicates your results to me, as either a paper, a PowerPoint presentation, a statistical dashboard (Google this, if you do not know what this is), a YouTube video, etc.  If doing a YouTube video, email me the link and include it in the written part you turn in.  (Obviously, you won't print out a video, but, as explained below, there is more to turn in, and a printed link should be included.)  For all other media, you must give me a hard copy.  PowerPoint presentations should be turned in as a printout of the slides -- also, if there is time, you can present the PowerPoint to me during office hours, but it must be before the deadline.  For PowerPoint printouts, black and white, reduced sized, images are fine, as long as they are readable.
-The suggested project involves obtaining data from the web, exploring the data, asking and answering questions with statistics, then communicating the results in a compelling way.  In addition to working with data, there can also be independent study, library research, interviews of statisticians, etc.  Part of your project could be learning a software tool useful for statistics or data science.  If you want to collect your own data, (I actually discourage this), you MUST do it in a scientifically acceptable way. If it sounds like a lot of work, it can be, but remember that these projects are optional and extra credit.  You will get some credit for anything you do along these lines, and anything you do will help you.

-If you are thinking of doing a project, please work with me to decide on a project topic.  We will also brainstorm ideas in class.  Pick a topic and a project that excites you.  Your project should relate to your passions, goals, dreams and/or interests.  My idea is that you will really want to do this project which is why I am giving you a lot of freedom to design it.  Getting extra credit is your excuse to do something that you would want to do, anyway.

 Suggested topics (actually, whatever interests you): sports (of various kinds, there are lots of free good data on baseball), entertainment, movies (again good data), law, criminology, government, city planning, architecture, weather, climate, geology, seismology, medicine, epidemiology, health, fitness, biology, evolution, extinction, ecology, math, computer science, statistics, data science, anthropology, ethnic studies, gender studies, history, sociology, culture, tourism, archeology, art, literature, writing, journalism, census, linguistics, finance, economics, business, astronomy, physics, chemistry, library sciences, theology, anything else you can think of.

 A more advanced technique is to use a "web scraper" which masquerades as a browser and pulls data directly from the web.  One student was successful at doing this last Spring (she used a website dedicated to this effort).  Some websites have their own Application Programming Interfaces (API) which facilitate this process (examples: twitter, facebook, linked in).  These more advanced techniques may be difficult, and often involve computer programming.   I am a computer programmer, but I do not have a lot of experience with web scraping.  That said, I have a lot of books on the subject and would love to learn how.  If you are interested, let's try it together during office hours.
-Last Spring, I gave some students extensive help on their projects.  Help does not count against you, even extensive help.  Many other students did not ask for help, and that is OK too.  Of course, some students chose to not even do a project, which was also fine.  (If you don't do a project, you won't get any extra credit, but it won't count against you, either).  Anything you choose is fine with me, but if you want help, ask early and come to office hours in the beginning, and all throughout the semester.  Things can get busy toward the end, both for you and for me.  Starting early will also give you more time, and you will need time to do these projects well.  You can also get help from other sources (family, friends, other professors, etc), but you must disclose the help you receive in writing in an "acknowledgements" section, when you turn it in.  That said, I encourage you to get help, if you need or want it, as long as you do not take credit for others' work.  Along these same lines, cite your sources.  You must also cite the source(s) of your data.

 Project proposals are due July 5.  Progress reports are due July 18.  Final project submissions are due August 4.  Final projects must have an addendum titled "behind the scenes" which describes how you did the project and where you got your data.  Optional sections could include "dead-ends" and "dreams for the future" for which you will get credit for things that did not work, or good ideas you had which you did not have time to implement. Creativity will be rewarded!
-Grades will be awarded as percentage points added to your final score.  Typically, this will be up to 3 percentage points.  However, last Spring, there were several truly exceptional students who went above and beyond, and I gave them 4 additional percentage points.  The separation between grades is 3-4 points (the scale I usually use is 93% gets an A, 90% gets an A-, 87% gets a B+, 83% gets a B, etc.) so doing well on your project will probably raise your final grade by one mark.  A score of 4 points could conceivably raise your grade by two marks, and even a score of 1 point or less could still raise your grade by one mark, if you are close to the boundary.   I plan to give grades this summer consistent with the grades I gave the last Spring.  In other words, I won't make any accommodations for the fact that you only have 6 weeks.  Please understand that doing a truly outstanding project in 6 weeks on top of successfully completing everything else on the statistics curriculum would be a colossal challenge.  But again, remember, these projects are optional and extra credit, and some extra credit is still given to less than outstanding projects.  And again, anything you do helps.

 '''Academic Integrity:'''  ''Cheating is not acceptable and will not be tolerated.''  Consider this:  in subtle ways, cheating to get a better grade on an exam can result in ''lowering'' the grades of some of your classmates.  Certainly this is true when a specific curve is used to assign grades.  Even when I don't use curves explicitly, they can be implicit in decisions about writing and grading exams.  As required by the policy of American University, I will report '''all''' suspected cases of cheating to the Dean's office who will proceed to investigate and adjudicate the issues.   Cheating is giving or receiving unauthorized assistance on exams, from other students or other people, from notes, from books, or from the web.  When inappropriate copying between students is caught, both parties may be culpable.
