**Thu Apr 24**

There will be a comprehensive “Review Exam” on the last day of class. * No new material *will be covered but all material this term is fair game. The purpose is to have you review the highlights of what we’ve covered during the term to refresh your memory. I will present a list of review topics during class Tuesday.

This review of material will go hand-in-hand with your final assignment because you need to review various techniques to assess what may be appropriate for your data analysis.

Note this is not the Final exam. There will be an optional take-home final (or an advanced project option) for those who need to make up a missed exam or want an opportunity to improve their grade.

**Due Fri Apr 25**

If you missed class Tuesday I described a final assignment. I will clarify here.

**1. Select a topic of interest.** This could be sports, politics, economics, business, stock market, current events, video games…anything that interests YOU. This should be related to a passion, hobby or something that you enjoy pursuing in your own time. One caveat is that the topic will need to offer some type of data for analysis.

**2. Collect data that can be used for analysis.** Search the web for relevant data. It won’t be perfect so don’t bother looking for the perfect data. Just find any data and we will do our best. More data is typically better but if there’s a mountain of data and you don’t know where to start I can help you take a random sample or otherwise limit the universe for analysis.

**3. Analyze the data using appropriate methods learned in class this term.** You could produce a simple descriptive analysis or you could conduct a hypothesis test, produce a confidence intervals or build a regression model. The key is to do something * appropriate* to gain a better understanding of the data or to make an argument about what the data is telling you. If you do the bare minimum your grade will be the bare minimum as well.

**4. Write a blog post describing your analysis.** Provide details regarding the data utilized and the analysis completed. If you considered other techniques but decided not to use them for some reason please explain your thought process. Use graphs, equations, tables, computer output etc as appropriate to present your analysis. What did you learn about your topic and the data collected?

For Tuesday please be prepared to tell me about your topic and to ask any questions.

*Step #4 must be completed by 5pm Friday, April 25th. *

**Due Tue Apr 15**
